The heart of the car is the engine because,
without it, the car is not going anywhere! However, carmakers are not just content with
putting an engine in the car. They want to put the best to outdo their competition! This is why Toyota is always working on its
car engines! The latest engine from the Japanese company
blows everything out of the water! What is the new engine released by Toyota,
and how powerful is it? Stay tuned as we bring you Toyota’s insane
new motor that changes everything! Toyota is among the top car makers globally! The company sold almost 10.5 million cars
last year, even when the whole industry was not doing so well, thanks to the Covid-19
pandemic and chip scarcity. How come Toyota has the trust of millions
of people worldwide? There are several reasons! Despite the competition getting hotter, Toyota
still makes quality cars, which makes them have models in the ranking of top automobiles
in almost every category. The company also makes a wide selection of
cars, so everybody will find something they want with a Toyota or associated badge! In fact, few automakers can match Toyota in
variety! Thanks to their high quality, Toyota cars
have a high resale value! You can even buy a used Toyota and expect
to get a decent price when selling at some point later! One more thing in favor of Toyota is the availability
of spare parts! You certainly don’t want to purchase a car
and then wait for months to have a replaceable part from the manufacturing country in case
you need a repair. The brand is widely popular all over the world. So, whether you drive a Toyota in a remote
area of South Africa or a town in Bangladesh, you will find spare parts available from your
dealer. Besides, mechanics that can handle Toyota
cars are everywhere, so you are assured you will get technical help when you need a repair! There is, however, another reason buyers rush
Toyota cars; the engine! Due to a focus on engine research and development,
Toyota has made the best in class engines that the market cannot quickly forget! The company made its first engine, the Type
A engine in 1934. That was two years before making its first
passenger car, the Toyota AA, in 1936. In May 1934, Toyota began creating prototypes
of the cast parts used in cylinder blocks and pistons for the Model A engine, which
was based on sketches of the 1933 model Chevrolet sedan engine. Creating the core1 of the water jacket, through
which cylinder block cooling water flowed, proved difficult. By referencing an oil core2 that company executives
had brought back from the United States, a cast cylinder block was finally completed
in August of the same year. Toyota completed the first prototype engine
on September 25, 1934. The parts manufactured in-house were limited
to cast parts including a cylinder head, cylinder block, and pistons, while imported Chevrolet
parts were used for crankshafts, camshafts, valves, plugs, and electrical components. However, when Toyota fitted the prototype
in a Chevrolet truck, the engine could only produce 48-49 hp during a driving test, instead
of the output of 60 hp that the Chevrolet engine produced. After referencing overseas documents and redesigning
the cylinder head to fit the swirl combustion chamber, the engine reached an output of 65
hp, eventually exceeding that of the Chevrolet! From that humble beginnings, Toyota has become
a master engine designer! For example, it made the 1JZ-GTE Inline-Six
engine, which produces 320 hp and 315 pound foot of torque. The Mk IV Supra actually owes its success
to the six-cylinder 2JZ-GTE underneath its hood. For more than two decades, the 2JZ's nearly
indestructible nature has been proven on applications pushing out as much as 2,000 hp. The brute of a cast-iron block makes all of
this possible and means as much as 750 hp can be yours with very few mods. Toyota also made the 4A-GE Inline-Four, rated
for 112 hp and 97 pound foot of torque. One of the first fuel-injected, four-cylinder
powerplants to feature a twin-cam, 16-valve layout, this mill was loosely based off of
Cosworth's legendary BDA series of engines. Nearly three decades later, the aftermarket
continues to support this classic four-banger as much as ever! However, with the release of the Dynamic Force
Engine, Toyota has taken its engine game to another level! This new engine is the new king of thermal
efficiency! To fully appreciate this new engine, it is
important to understand gasoline thermal efficiency. The term is how much of the potential energy
in gasoline gets converted into power that can be used to move your vehicle. Internal combustion engines do this by injecting
that gasoline in a fine spray in a mixture with air in the cylinders, the piston squeezing
it into as small a space as possible, and lighting it with a spark. When it ignites, it explodes and expands,
pushing the piston back out with incredible force, and the pistons turn the crankshaft,
which is connected to the transmission, which is connected to the drive shaft, which is
connected to the wheels, with various parts and gears in between directing and controlling
the power to make sure the wheels turn, but not so fast that they simply spin faster than
the tires can handle. However, there is a problem with the setup
just described! When the combustion takes place, some of the
power is lost to friction and excess heat. This renders the average gasoline combustion
engine running at about 35 percent thermal efficiency! Engineers have been working tirelessly for
more than a hundred years to reduce the energy wasted and convert as much of that energy
in gasoline to moving the car or powering your AC. What the engineers at Toyota did was look
at every stage of the engine’s cycle and tried to find ways to make it not only more
efficient in terms of saving gas. They then looked for how to convert that saved
gasoline into more power, increasing the thermal efficiency. Toyota looked for inspiration from a place
where efficiency is paramount; Formula 1! The company borrowed several technologies
from the racing cars to achieve high-speed combustion. Three changes, in particular, helped Toyota
to accomplish high-speed combustion and ensure the air-fuel mixture burns more completely,
which produces more power with every combustion. One of the changes is the angle of the intake
valve, laser clad valve seats, and the proportions of the cylinder. The angle of the intake valve and shape of
the intake port guide the air-fuel mixture in a specific pattern to spread it more evenly
within the cylinder, so it combusts more quickly and more evenly, producing more power and
less waste. Secondly, the laser-clad valve seats allow
for optimized valve angle and airflow direction to create “tumble flow,” a more controlled
swirl pattern in the combustion chamber that distributes the air-fuel mixture more evenly
ahead of the compression phase. Third, a taller, narrower cylinder means the
igniting mixture takes less time spreading across the cylinder, again speeding up that
combustion moment, and more of its force pushing the piston down, which provides more torque
and greater efficiency. Toyota engineers didn’t just stop there,
as they made use of additional tried-and-tested strategies to maximize the thermal efficiency
of the new Dynamic Force engines. Toyota’s D-4S fuel injection incorporates
both direct and port injection, the two systems combining to provide greater efficiency and
smoother operation during normal driving but relying solely on direct injection when maximum
power is needed! Meanwhile, the pistons themselves have a special
finish to reduce friction, an electronic thermostat works in concert with an electric water pump
to regulate temperature for peak efficiency, variable valve timing ensures optimal power
vs. efficiency, and a higher compression ratio further increases efficiency. All these strategies culminate in a world-best
41 percent thermal efficiency in hybrid applications and 40 percent in gas-only vehicles, with
more torque and power at any engine speed, and better fuel efficiency and emissions! The new Dynamic Force engine helps Toyota
to fight for every percent in the efficiency race. The 2.0-liter four is compatible with the
new six-speed manual transmission Toyota has developed for global needs. The transmission is more compact and lighter
than Toyota’s current unit and incorporates rev-matching capability. Toyota has equipped the 2022 Toyota Camry
with the Dynamic Force engine. The engine is tuned to make 209 PS and 253
Nm, which means 25 PS and 8 Nm more than the outgoing port injection Camry. Thanks to this new engine, the 2022 Camry
now blows the like of the Honda Accord away when it comes to acceleration. The car pulls hard where the Accord runs out
of breath! Wap Car took the car for a spin, doing over
300 km of what they called hard driving. The Camry averaged 7.7-litre per 100 km which
is definitely impressive considering the kind of road, traffic, and speeds the car was doing. The Camry’s naturally aspirated engine also
makes it much more satisfying to string together a sequence of bends. Let’s hear what you think of Toyota’s
new dynamic force engine in the comment section below!
