In a closed-loop setup, the engine circulates engine coolant (typically a 50-50 mix of antifreeze and distilled water) through its water jacket, just like a car engine. Instead of dumping raw ...

Evans Cooling Systems has developed its NPG+ coolant that has a lower surface tension than EG/water, boils at 369 degrees at atmospheric pressure, and allows the coolant to remove more heat from ...

The cooling system itself is complex and relies on many smaller individual parts that work together to keep the engine running optimally, including the diminutive yet supremely important thermostat.

Besides pre-announcing the 3.0L Duramax when unveiling the 2019 Silverado and Sierra light duty trucks at the end of 2018/beginning of 2019, GM has remained very tight-lipped about the diesel engine.

Automotive manufacturers and engineers have paid attention to promoting engine performance with low emissions satisfying many emission regulations. With such goals in mind, we have investigated new ...

Though the rotary diesel never really got beyond the prototype stage of development in the past, the concept has merit. It's a lightweight, compact engine with a good power-to-weight ratio.
