2. Diesel exhaust - Wikipedia

   en.wikipedia.org/wiki/Diesel_exhaust

   Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates. Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator ...

3. Crossflow cylinder head - Wikipedia

   en.wikipedia.org/wiki/Crossflow_cylinder_head

   A crossflow head gives better performance than a Reverse-flow cylinder head (though not as good as a uniflow), but the popular explanation put forward for this — that the gases do not have to change direction and hence are moved into and out of the cylinder more efficiently — is a simplification since there is no continuous flow because of valve opening and closing.

4. Ontario's Drive Clean - Wikipedia

   en.wikipedia.org/wiki/Ontario's_Drive_Clean

   Ontario's Drive Clean is an automobile emissions control program introduced by the Government of Ontario and came into effect April 1999. The program was initially intended to weed out vehicles producing unrestrained amounts of particulate emissions contributing to smog and increasing pollution.

5. Electronically controlled unit injector - Wikipedia

   en.wikipedia.org/wiki/Electronically_controlled...

   It performs the same function as a conventional unit injector in an internal combustion engine, such as in an on-road or off-road vehicle or a diesel-electric locomotive. The pressurized delivery of fuel is camshaft -driven, but the timing of the injector's internal operations are controlled by the engine control unit so as to achieve certain ...

6. Turbo-compound engine - Wikipedia

   en.wikipedia.org/wiki/Turbo-compound_engine

   The power-recovery turbine sits underneath a two-stroke diesel engine. A turbo-compound engine is a reciprocating engine that employs a turbine to recover energy from the exhaust gases. Instead of using that energy to drive a turbocharger as found in many high-power aircraft engines , the energy is instead sent to the output shaft to increase ...

7. Lean-burn - Wikipedia

   en.wikipedia.org/wiki/Lean-burn

   Lean-burn refers to the burning of fuel with an excess of air in an internal combustion engine.In lean-burn engines the air–fuel ratio may be as lean as 65:1 (by mass). ). The air:fuel ratio needed to stoichiometrically combust gasoline, by contrast, is 14.
