We created this program to help you better
serve your customers with gasoline direct injection engines. GDI engines have a problem
that can seriously hurt your customers vehicle performance and fuel economy, but the solution
is fast and easy for you and it's affordable for them. To go through the program use the navigation
buttons at the bottom right and watch for a couple of quick quizzes along the way. Let's get
started. In the past decade gasoline direct injection engines have become extremely popular
with both domestic and import auto manufacturers. Compared to conventional fuel injection, GDI
can deliver improved fuel efficiency more power from smaller engines and reduced emissions at
low load. That's great, but the popularity of GDI engines has brought back an old service issue:
carbon deposits that can rob drivers of horsepower gas mileage and smooth operation. So why do
carbon deposits happen in GDI engines and how can you help your customers? Let's have a look.
Conventional multi-point fuel injection injects fuel into the intake tract or cylinder port at low
pressure. With gasoline direct injection, or GDI, a common rail fuel line injects highly pressurized
gas directly into the combustion chamber of each cylinder. The improvements in power and fuel
economy come from the extremely precise control that GDI engines have over the amount of fuel
delivered and injection timing. Fuel and timing are adjusted multiple times per second according
to engine load, plus some GDI engines operate on full air intake with no air throttle plate, which
further improves efficiency and reduces piston pumping losses. Instead of having a throttle plate
that restricts the incoming air supply, the engine speed is controlled by the ECU and the EMS which
regulate fuel injection function and ignition timing, but as with many technology advancements
there's also a downside. When conventional multi-point fuel injection injects fuel into the
intake tract or cylinder port, gasoline washes over the back sides of the valves. Modern gasoline
with its package of detergents is an excellent cleaner, so in conventional engines gasoline
keeps the back sides of the valves clean and free from deposits, but since GDI engines inject gas
directly into the cylinder, gas never reaches the back of the valves. When fuel is no longer washing
the intake valves on the way to the cylinder, small amounts of dirt from intake air and blowback
carbon from the crankcase ventilation system build up and burn onto the intake walls. The result is
carbon deposits forming on the valves, cylinder heads, and injectors and that's where the trouble
begins. Over time the carbon buildup on the intake valves reduces the air flow to the cylinders and
that reduces torque and horsepower and hurts fuel economy. The carbon deposits on the cylinder
and cylinder head can cause pre-ignition, rough starting, and rough idling as well as foul spark
plugs and misfire codes. The build-up can become so severe that pieces of carbon can actually break
off and burn a hole in the catalytic converter. Many modern GDI engines face a double challenge
because they're variable valve timing keeps the valves open longer to maximize the scavenging
effect and minimize emissions. That leaves the valves exposed to carbon particles in the cylinder
longer and that means more carbon buildup. How big of a deal is the GDI carbon deposit
problem? It's big and it's becoming huge. Gasoline direct injection was actually first
invented in 1902 by the French inventor Leon Levavasseur who also produced the world's first
V8 engine, but as of 2008 only 2.3 percent of passenger vehicles used GDI engines. By 2015
the number was up to 45%. By 2021 roughly 80 million vehicles in the US will have GDI
engines and more cars with GDI engines, means more service issues related to carbon
deposits and that means more customers who need a solution. Until recently removing carbon
buildup on GDI intake valves had been difficult and costly. Labor-intensive processes such
as walnut-shell blasting and manual valve cleaning required an engine teardown to access the
valves. It was hard work and a very hard sell to many drivers. Before GDI engines became popular
fuel additives were used to treat carbon buildup, but with GDI neither the additives nor the
fuel would reach the back of the valves, but CRC has an affordable solution that
your customers can easily get on board with. Scientists have found that the chemical polyether
amine or PEA, when applied in strong concentration and under the right conditions, can effectively
clean hardened carbon deposits from GDI valves and other engine surfaces without blasting brushing or
any teardown required. CRC has used this discovery to create a GDI carbon deposits solution that
allows you to tackle the problem quickly, easily, and at a very reasonable cost. CRC GDI IVD
intake valve and turbo cleaner is an aerosol spray that's applied through the engines air intake or
throttle body and delivered directly to the backs of the GDI intake valves. CRC GDI Valve & Turbo
Cleaner contains the highest concentration of PEA available on the market to provide the fastest
most thorough chemical cleaning available. A single application removes up to 46 percent
of carbon deposits in the first 60 minutes. With the ability to clean heavily baked-on
carbon deposits the way it does, you might ask, "Is it safe?" Yes, CRC GDI Valve & Turbo Cleaner
is safe and effective for all gas-powered engines including turbocharged and supercharged engines.
It's safe to use every 10,000 miles or at every oil change and it's safe to use for O2 sensors and
catalytic converters, but it should not be sprayed directly on a mass airflow sensor and should not
be used in diesel engines. High temperatures can cause carbon to stick to turbocharger turbines,
housings, and waste gates. The turbine blades and oil seals are fragile and carbon buildup
can eventually cause significant damage, but the same cleaning action that removes carbon
deposits from valves and pistons cleans turbo impellers as well. On turbo engines CRC GDI Valve
& Turbo Cleaner can be sprayed directly through the throttle body or through the air intake, but
again never directly on a mass airflow sensor. Okay here's some real-world independent lab
results that prove the effective cleaning power of CRC GDI Valve & Turbo Cleaner. Here's a 2011
Hyundai Sonata cylinder-head before treatment. Before treatment, the carbon deposits average
9.89 mm in thickness. You know that's going to contribute to a tendency for pre-ignition.
Now here's that same cylinder head after an hour of treatment with CRC GDI Valve & Turbo
Cleaner. The carbon deposits are nearly gone. The average thickness is down to 1.85 mm.
The deposits were reduced by 85 percent, after the first hour. Now have a look at the
intake valve from the same Sonata. After the first hour of treatment the deposits are reduced by
24 percent. Take a look at these fuel injectors, also from a 2011 Sonata. Before treatment they're
heavily caked with carbon and the flow is being impeded around the injector orifice. After
the treatment the valves look almost new, 100 percent of flow has been restored, and
the spray pattern and fuel droplet size are once again optimized for increased fuel economy.
Here's a cylinder top from a 2009 Cadillac CTS. Carbon deposits average 8.59 mm in thickness.
After the first hour of treatment, the deposits measured 2.77 mm, a 68 percent reduction in
deposit thickness. You might wonder why these test results say "after the first hour." That's
because the carbon cleaning action will continue for several days after the treatment. As the car
is driven additional carbon that's been loosened by CRC GDI Valve & Turbo Cleaner is safely removed
by the heat and pressure of engine operation. Take a look at these dynamometer results for a 2015
BW Passat 1.8 i4 Turbo. The vehicle measured an impressive 5.6 peak wheel horsepower gain
two days after treatment, but it picked up an additional six point nine peak wheel horsepower
gain when measured eight days after treatment. Here's another bonus CRC GDI Valve & Turbo Cleaner
will also work to clean carbon deposits off spark plugs without the need to remove them from the
engine. And finally here's proof that CRC GDI Valve & Turbo Cleaner does really work for
turbos. Here's a 2013 Mini Cooper Countryman turbo impeller before treatment and here it
is after treatment. The results are dramatic. You can see all our test results at
CRCforshops.com. The tests are real and so are the results CRC GDI IVD Intake Valve & Turbo
Cleaner really does remove tough carbon deposits from valves, piston heads, fuel injectors, and
intake manifolds quickly, safely, and without an engine teardown. First, just as you would with
any product, read the entire product label before using so you can understand the instructions and
the safety guidelines. Next, warm up the engine CRC GDI Valve & Turbo Cleaner requires a period
of heat soak to work so you want to start with an engine that's fully warmed up. Locate the throttle
body or air intake and spray the product directly through the throttle body. If the throttle body
is not easily accessible, spray past the mass airflow sensor, but do not spray into the mass
airflow sensor assembly. You can also remove the mass airflow sensor assembly and spray where the
sensor is mounted. If the vehicle is turbocharged, you can remove the booster sensor and the charge
pipe and spray into the pipe. If it's easier you can also spray into the vacuum port. Lift the
permi-straw dual action spray system and lock it into place. With the engine running at 2,000
RPM spray in short bursts until the can is empty. Once the can is empty, rev the engine two to three
times, but don't exceed 3,500 RPM. Run it idle for one minute then turn the engine off. Reassemble
the air intake system and let the engine heat soak for a full hour. The heat soak is critical so be
patient and let the CRC GDI Valve & Turbo Cleaner do its work. After the hour is up, restart the
engine and drive at highway speeds for at least 10 minutes and remember as our tests showed the
maximum benefit is achieved when the vehicle is driven regularly over the next several days, so
let your customer know they should drive the car regularly over the next week or so. If you have a
vehicle with severe carbon buildup CRC GDI Valve & Turbo Cleaner can even be used in successive
treatments. Just have your customer drive about a thousand miles before a second treatment in order
to get the full benefit of the first treatment. GDI engines are not the only engines
that get carbon deposits. Conventional fuel injected and carbureted engines
can suffer from carbon buildup too. CRC GDI Valve & Turbo Cleaner is safe for use in
engines with port fuel injection or carburetors. You can apply the product in the same way as
you would on a GDI engine, right through the air intake. For automotive service providers the GDI
carbon deposit issue means an expanding service opportunity. Any time a customer comes in for
an oil change or a regularly scheduled service, suggest treatment with CRC GDI IVD Intake Valve
