As long as the internal combustion engine has existed, engineers have been trying to find better ways of igniting the highly combustable mixture of air and gasoline that powers cars. Everything from ...

Bosch managed to create a timeless design when it introduced spark plugs to the masses. But it would have never come to pass if not for another invention.

Spark plugs can only ignite the fuel at one end of the chamber. A laser ignites the fuel in the middle of the chamber instead, burning more of the fuel and improving combustion efficiency by 27 per ...

Most pickup trucks sold today have internal combustion engines. Passenger vehicles are powered by two main types of engines: compression, aka diesel, and spark ignition, aka gasoline. Besides the type ...

[Dan] wanted to learn a bit about solid state ignition in engines; to get started he needed a test subject, so he decided he would upgrade his old 12 horsepower lawnmower. Originally the lawnmower ...

Mazda's powertrain team has brewed up a fancy new engine that, like a diesel, uses compression to activate the combustion process. In a press release on the new tech, Mazda tells us just how ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

The pollutant emissions and high-energy consumption of combustion engines using conventional spark plugs have long been serious environmental problems. Now, it has been demonstrated that lasers can ...

If you find you're changing spark plugs way more often than you expect, it's clear there's something wrong somewhere in your ...

Man, time flies. It seems like just a couple years ago when GM introduced the first major renovation of its small-block, but of course, that was back in 1991 for the '92 Corvette. At the time, one of ...

Homogeneous charge compression ignition (HCCI) engines combine a diesel's torque and fuel efficiency with a gas engine's cleaner emissions. The HCCI technique has been a goal of automakers since the ...
