Internal combustion engines aren't going away anytime soon. And since a practical alternative can't be ready for use within the next few years, we need a better internal combustion engine in the meantime.
Four strokes, less fuel. How's that sound? With the addition of just a couple of linkages, an Atkinson cycle engine can complete all four strokes with a single rotation of the crankshaft.
The Grail Engine takes a variety of modern, cutting-edge engine technologies and puts them all together in one package. Honda and Ford have already shown interest -- should the rest of us?
Car engines that run on gasoline aren't the only kind of internal combustion engines. Learn about the types of internal combustion engines in this article.
Today, hot bulb engines are a mainstay for serious antique engine collectors and represent a historic landmark in the evolution of gas engines. Efficient, simple and robust -- hot bulb engines had it all.
You may think your dreams of fuel economy can be fulfilled only by a car with a diesel engine, but direct injection engines offer another option for high efficiency and performance. How do they differ from standard gas engines?
It's possible that someday there may be no need for a lot of the components that you currently find under the hood of a car or truck. That is, if the vehicle is equipped with in-wheel electric motors.
High gas prices are driving people to look at alternatives to fossil fuels, such as a turbine designed by the father of alternating current, Nikola Tesla.
When you hear the word "diesel" you probably imagine something along the lines of a Mack truck. But what do powerful diesel engines actually look like? Check out this image gallery to see the cutting-edge diesel engines in development today.
Car engines range from small, economic 4-cylinders to insanely powerful 16-cylinder beasts. Get revved up with full-throttle photos of how they all work.
