Is your engine underperforming? Our expert shares how a diesel engine compression test could provide the diagnosis.

Toyota Patent Suggests a High-Compression Diesel Truck Engine May Be in the Works With Toyota shifting away from V8s, this could be its answer for smaller displacement and high torque figures.

The first Diesel engines were started 130 years ago, but they have moved a long way since then. Like their gasoline counterparts, the compression ignited engines have evolved from the rough units ...

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.

High compression, typical of diesel engines, is no longer needed to make the fuel ignite; in fact, the chemistry causing this auto ignition process exists only at lower compression ratios.

What Are Naturally Aspirated Diesel Engines? Unlike gasoline engines, which rely on spark plugs to ignite the air-fuel mixture, diesel engines use compression ignition. This process involves ...

The big news is that Infiniti's power goal for its diesel-killing 2.0-liter variable compression turbocharged four-cylinder is 268 horsepower, and the torque target is 287 lb-ft.
