A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand how ...

For hundreds of years of human history, the invention that has defined our ability to travel, explore, and expand our boundaries has been the combustion engine. This hallmark of mechanical development ...

If you're a follower of the "How It Works" series, you've been learning the principles of what makes a car run. You've boned up on the four-stroke cycle, valvetrains, cooling, lubrication, and ...

In-cylinder heat flux, cylinder pressure, and flame arrival and position data were obtained at air fuel ratios ranging from 11-16 at 3060 rpm and approximately 80% load. The engine used was a single ...

It's important to keep in mind that the combustion process occurs in a very brief period of time. Due to a variety of conditions that include mixture density, homogeneity, temperature, fuel ...

starts with the piston at the top of the cylinder (TDC) and the intake valve open to admit air and fuel. At bottom-dead-center (BDC) the inlet valve is closed and the compression stroke (b) starts.

Developing new engines that perform better, weigh less, use less fuel, and meet stringent emissions standards is the primary goal of most engineers and automotive corporations. Companies continually ...

You may have heard your car has a four-stroke engine, but you're not sure what that means. Why are there four? And what is a stroke, anyway? A modern gas engine most commonly uses pistons and a ...
