In this video, we're doing a detailed comparison of petrol, or spark ignition, and diesel, or compression ignition engines.

Diesel engines don’t have spark plugs; instead, they use the super-heated air created by their high compression ratios to ignite the diesel fuel as it’s injected into the cylinder.

As an engineering student in late 19th-century Bavaria, Rudolf Diesel found little promise in steam and internal combustion ...

Two primary types of internal combustion engines exist: a spark ignition gasoline engine and a compression ignition diesel engine. Spark ignition and compression ignition differ in how each delivers ...

The ignition system provides a properly timed spark to burn the air/fuel mixture for the power stroke of the four-stroke cycle. An eight-cylinder engine at 6000 rpm needs 400 sparks a second!

The addition of a spark plug in place of the original fuel injector and fumigating natural gas (NG) inside the intake manifold is an economical way to convert heavy-duty diesel engines to NG ...

These parts work together to create a controlled explosion that turns the wheels of vehicles. Though internal combustion engines are still the most common type of engine in use today, they do have ...

When Japanese automaker Mazda debuted the fourth-generation Mazda3 in 2019, it came with the brand's Skyactiv-X engine. This revolutionary powerplant combines the attributes of spark ignition and ...

The 5.7 HEMI is a high-quality engine, but it's vital to know how often to change the spark plugs for optimal performance. Here's the suggested intervals.

Diesel engines have pistons that look different from the ones you'd see with a gas engine. There's a reason why that's the case, and it's all about performance.
