The Honda Civic Type R Destroys The Competition - The Best Engines

Jun 05, 2021
Hello everyone and welcome, in front of me is the Honda Civic Type R engine. This is a two-liter turbocharged inline four-cylinder, but before we get into this engine, I want to talk about the Honda Civic Type R because the car is giving some pretty incredible features. numbers now, if everyone takes the August 2018 Motor Trend assigned reading material and turns to pages 52 and 53, you'll see what I'm talking about, so Motor Trend did back-to-back testing with the Ford Focus RS, the Honda Civic Type R, the subaru wrx sti

type

ra and the volkswagen golf r now the numbers are quite fascinating because the front wheel drive

honda

civic

was faster to 60 miles per hour than the all wheel drive golf r and the all wheel drive subaru sti and a 70 miles per hour was faster than the ford focus rs also with all wheel drive and was one second faster to 100 miles per hour compared to all cars almost two seconds faster to 100 miles per hour compared to the golf r in The quarter mile loses to the Ford Focus RS by two-tenths of a second, but has a trap speed almost five miles per hour higher.

The Civic has the

best

braking of the group. The only car of the four that stops from 60 miles per hour to zero and less than a hundred feet, the Civic also ties for the

best

lateral GS along with the Ford Focus RS at 1.01 GS. Now here's the real trick, so they took the four cars around the tracks on the streets of Willow and the Honda Civic. The Type R was the fastest and beat the Ford Focus RS by over a second and beat the STI Type Ra and Golf R by over two seconds and it's doing all this for a lot less money, fifty six hundred dollars less than the the next cheapest competitor and fifteen thousand dollars less than the limited edition subaru sti

type

ra now the

civic

type r is the only front wheel drive car of the group and this helps it save weight, it weighs approximately 300 pounds less than the other cars and On second thought, maybe it's smaller than the other cars, actually it's not, it has the longest wheelbase and the widest track, it has the most rear legroom and it has the second largest cargo space of the group and thanks to two-wheel drive. platform and the efficient 2-liter engine, it actually has the best combined fuel economy rating of the group, looks of course are subjective and the core is front-wheel drive, so whether or not you think front-wheel drive it's more or less fun, uh than the others Honda has certainly shown that it can be done from a level of performance that can be compared to all-wheel drive vehicles.

More Interesting Facts About,

the honda civic type r destroys the competition the best engines...

He has the fastest car on the track of the group. It has possibly the most practical car of the group. The most efficient car of the bunch and it does all this at the lowest price by far, which in itself is very impressive, so now let's start talking about the engine. In fact you can buy them as a crate engine for sanctioned racing applications and put it in whatever you want as long as you use it on the track as mentioned above this is an inline four cylinder engine you can see here it is turbocharged and You can also see that it has an aluminum block and a forged crankshaft with aluminum cylinder head and forged connecting rods.

You can also see that the exhaust manifold is actually integrated inside the cylinder head, so it exits directly to the turbocharger. This saves weight and creates a smaller overall package, it also helps with turbo response and helps improve piston emissions. The interior is cooled by oil jets and they also have internal cooling galleries that are used to help reduce piston ring temperatures. Now Honda claims that this is the same technology they use in their Formula One

engines

for the pistons, which means it's reliable - wait, no, that's it. Right now, not looking under the valve cover and looking at the valve train, you can see that we have two overhead camshafts and these are actually chain driven.

Now these camshafts are actually hollow, they have thin walls and they do this to reduce weight and rotational inertia. and when it comes to this chain drive, Honda claims that it was designed to last the life of the engine, so it is supposed to never require any maintenance. Each camshaft has variable timing control so you can change the valve phasing for both the intake and exhaust you can also see it has vtec here on the exhaust camshaft so you can see the lower profile there and then the higher lift profile here compared to the intake camshaft it only has a single cam profile and the reason for this is that it is turbocharged.
I don't actually need the extra lift to push air into the engine. The turbocharger does a good job of pushing that air into the engine, but on the exhaust side, after combustion has occurred, you have that really high internal pressure and then. You are also working against the turbocharger as you try to expel the exhaust. You want to try to reduce the resistance of those exhaust gases, so allow for a higher lift cam profile to help get those exhaust gases out at higher rpm. Now, speaking of the exhaust, the exhaust valves are actually full of sodium, so the reason Honda does this is to help keep them cooler so the sodium inside helps transfer heat away. of the valve head.
Now Honda claims that because they use these full of sodium. valves, they can actually run a slightly leaner air/fuel mixture because they don't have to rely on a rich air/fuel mixture cooling the exhaust valves as much and by using that slightly leaner air/fuel mixture they get a better efficiency and better power as far as possible. The intake is a high twist intake and Honda has gone with a higher pressure direct injection fuel system and they claim that by using the direct injection system they have actually increased torque throughout the rpm range along with the direct injection that they have chosen. use smaller spark plugs, so they are actually 12 millimeters wide compared to traditional 14 millimeter spark plugs, and the reason they have done this is to allow more space inside the combustion chamber and, in fact, save a little weight with the spark plug so that I have more room for the valves and the direct injection system, so here you have a traditional spark plug removal tool and here you can see that it doesn't even fit, it doesn't work to remove the spark plug, it's too small, you need a Now, smaller in size, the engine is designed to have very little maintenance requirements, so for the first hundred thousand miles all you have to do is change the fluids and filters and then, after After 100,000 miles, you'll want to have your water pump inspected.
You're going to want to get your valves adjusted and you're going to want to replace your spark plugs, so now let's start looking at the differences between the Accord engine and the Type R engine, starting with horsepower and torque, so here we are . Looking at a dyno diagram we have horsepower and torque on the left and then we have the engine rpm here at the bottom and in green we have the agreement, the solid line is torque, the dotted line is horsepower of power and then in red we have the solid line is the torque for the type r and then the purple dotted line is the horsepower for the type r and as you can see the accord actually starts with more torque and faster , so it actually has a smaller turbocharger and revs up a bit. faster and reaches peak torque before 273 pound-feet at just 1500 rpm, where it goes up to 2500 rpm for the Honda Civic Type R, which is 295 pound-feet, so it's a little more torque, but a little later after that.
Of course, the Type R's power surpasses that of the Accord, peaking at 6,500 rpm: 306 horsepower compared to the Accord's 252 horsepower at 6,500 rpm. Now the Type R accelerates up to 7,000 compared to the Accord, which stops at 6,800. As mentioned, the Accord's turbocharger is a little smaller, so it has a lower inertia turbine, so it spools up a little faster and also uses a more aggressive angle on the turbine blades to help spin. at low revolutions. It now provides less boost so the Accord is maxing out at 20.8 psi compared to the Type R which has 22.8 psi and the small difference along with the different ignition timing means that the Accord's engine runs with regular gasoline compared to the Type R engine that runs on premium gasoline.
Now both

engines

have compression. ratio of 9.8 to 1, but the accord actually has different pistons than the type r engine and also has a completely different fuel system that has a lower flow and is more about control than fuel flow high flow for those higher horsepower figures than the r type engine. has and one last major differentiator between the Accord and the type of engine is that the Accord engine actually has balance shafts built into the oil pan, so it helps eliminate those second order vibrations, whereas in the type r They do not have balance axes. They embrace that extra vibration for a little more horsepower.
