The engine'sfuel systempumps gas from the gas tank and mixes it with air so that the proper air/fuel mixture can flow into the cylinders. Fuel is delivered in modern vehicles in two common ways: port fuel injection and direct fuel injection. In afuel-injectedengine, the right amount of ...
In fuel injection systems used on some engines, gasoline and air are mixed in the intake manifold.A fuel pump is piped to draw the carburetor outside the gasoline can.The pump may be a mechanical engine operation - or it may be electric, in this case usually beside or even inside the ...
Remember that the diesel engine has no spark plug that intakes air and compresses it; instead it injects the fuel directly into the combustion chamber (direct injection). It is the heat of the compressed air that lights the fuel in a diesel engine. In the next section, we'll examine the...
See How Fuel Injection Systems Work for a lot more detail on what the ECU does. The pins on this connecter interface with sensors and control devices all over the car. A modern ECU might contain a 32-bit, 40-MHz processor. This may not sound fast compared to the 500- to 1,000-MHz...
A mid-1985 upgrade brought a larger 1.9-liter (113.5 cid) "CVH" with 86 horsepower in carbureted form or 108 with option electronic port fuel injection. The latter was newly standard for GT, which gained its own asymmetric body-color grille, aluminum wheels, bigger tires, rear spoiler, and...
out of the cargo plane. Among those on board was an expert maintenance crew, so if there was a mechanical problem on the flight, there were plenty of people to take care of it. The investigation report at the time surmised, once again, that the plane had run out of fuel [source:...
It might have been quicker still with Bendix mechanical fuel injection, but that promised option never materialized. No matter. With 9.75:1 compression, the Rebel drank premium fuel and a fair bit of it, which hardly fit Rambler's economy image. And at $2786 it was the costliest '57 ...
Unfortunately, air alone can't be used as a fuel. First, energy has to be stored in it by squeezing the air tightly using a mechanical air compressor. Once the compressed air is released, it expands. This expanding air can be used, for example, to drive the pistons that power ...
In scientific terms, a car is an energy converter: a machine that releases the energy locked in a fuel like gasoline (petrol) or diesel and turns it into mechanical energy in moving wheels and gears. When the wheels power the car, the mechanical energy becomes kinetic energy: the energy ...
