Engine

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.

Limp Mode allows your car to be driven a limited distance at reduced speed when something is wrong and may cause severe damage or stop the vehicle from running.

A ticking noise from your car is most likely related to the engine, but it could also be coming from something else.

While tracking down the source of the squeal can be difficult, a good place to start is by identifying the circumstances under which the squeal occurs.

Although most engine oil and gasoline varieties work fine on their own, sometimes they could use a little help with an additive.

Mild-hybrid vehicles work on the same principle as traditional hybrids, but with less power from the electric motor, which assists the gas engine.

Cold weather adversely affects diesel engines more than gas engines, but that’s only partly due to the engine itself.

An engine oil pump failure affecting some 139,700 Focus and EcoSport vehicles is the culprit.

Your car’s water pump circulates coolant throughout the engine, where it soaks up heat, and into the radiator, where the coolant is cooled and then recirculated back to the engine to start the process over again.

Software for the knock sensor detection system was not installed at the time of manufacture, which may not prevent an engine compartment fire while driving.
