Racecar diesel engines and their horsepower ratings

[admin]

There are many among us who are crazy about the sports cars and the various car racing events. After all, who would not love the sight of cars with spectacular designs making rounds at the circuit at lightening fast pace. However, there remains a question in this regard.

Have you ever thought why the Racing cars have a higher speed as compared to the ordinary vehicles? In addition, what is the reason behind the racing cars having a much higher stamina than the ordinary cars that we use in our day to day life?

Well, the answer is simple and it does not need any specialist to understand the basics of such a high stamina of the racing cars. It is because the racing car diesel engines have been modeled in such a way that it helps the car to achieve a higher speed.

An 11-liter diesel engine of a car has a long stroke, which denotes that the piston is moving a relatively long distance up and down in its cylinder on each cycle in comparison to the usual cars that we use. A racing engine has comparatively a short stroke compared to the ordinary cars with a long stroke. A Racing engine’s piston has comparatively a large diameter than compared to the engine size. This bigger piston goes up and down within a comparatively short distance on each cycle.

This phenomenon makes a racecar engine run much faster on the roads. The speed can be pulled up to 15,000 RPM for a Champ Car engine. However, these cars have relatively little torque. Generally, a diesel engine with a large body cannot raise its stamina above 2,000 RPM, but the huge torque and the long stroke helps it a lot. The torque helps the engine pull up a huge load while the user is on the upwards journey.

An engine naturally produces torque. This is common to all automobile engines. Say, in a gasoline engine, when the ignition of gasoline occurs, it pushes the piston on, and then the piston puts pressure upon the crankshaft, causing the crankshaft to turn. The conditions that affect the torque are the size of the piston face, the amount of exerted pressure the ignited fuel uses to the face of the piston and the traveling distance of on each stroke. The torque rate, thus, depends on the large diameter of the crankshaft and the big size of the lever arm.

One can calculate and convert torque into horsepower following a simple equation:

HP = Torque * RPM / 5,252

Now if we talk about the race cars, their construct with carbon fiber bodies, incredibly hi-tech engines, ultra-advanced aerodynamics & intelligent make of the electronic parts enables each and every car to achieve a fairly high-speed. As a race Car runs at 240 mph speed and above, the driver of the car often experience the G-forces and has to cope with the incoming data so quickly which makes the Champ Car driving one of the most challenging professions in the world of sporting.

One of the favorite sports in the world, the sport is really quite exciting when the driver is on speed. Many a times, the racing teams need to create cars that are quite flexible to run under any given condition.

Those teams need to revise the aerodynamic package completely, check all the suspension settings and the other parameters, which generally makes a car ideal for the racing.
The drivers need to be extremely nimble in order to handle the conditions they generally face.
