EGR valve the top of box on top of the inlet manifold of a Saab H engine in a 1987 Saab 90. In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO x) emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. [1]
English: A diagram showing the airflow through the nacelle of the SR71 Blackbird as the speed increases from zero to Mach 3.2. This image is based on Figure 1.21 from the SR-71 Flight Manual. Русский: Схема движения воздушных потоков в мотогондоле самолёта Lockheed SR-71 при ...
Scavenging is the process of replacing the exhaust gas in a cylinder of an internal combustion engine with the fresh air–fuel mixture (or fresh air, in the case of direct-injection engines) for the next cycle. If scavenging is incomplete, the remaining exhaust gases can cause improper combustion for the next cycle, leading to reduced power ...
The power produced by an engine increases with the engine's RPM to a maximum, then falls away. This is known as the point of maximum power . Given a curve describing the overall drag on the vehicle, it is simple to find the speed at which the total drag forces are the same as the maximum power of the engine.
This significantly reduces engine performance, since the circular piston rings are unable to properly seal against the oval-shaped cylinder walls. The amount of sideways force is proportional to the angle of the connecting rod, therefore longer connecting rods will reduce the amount of sideways force and engine wear.
