Engines

What is the result of changes in moder engines?

• The catalytic converters absorb many exhaust pollutants

• The exhaust pollution levels are lower by the increasing use of special filters called catalytic converters.

• The result of changes in moder engines, the power and performance of a modern engine are increased, and the level of pollution is reduced.

Who invented the rotary-combustion engine?

What is the most common type of alternative engine?

• diesel engine

• rotary-combustion engine

• steam engine

• carbon engine

Wankel debeloped the rotary-combustion engine in the________

• 1940s

• 1950s

• 2000s

• 1970s

What do the catalytic converters do?

• absorb many exhaust pollutants

• heat the compressed fuel/air mixture to the point where it explodes

• compress fuel and air

Name the 4 stages of the Wankel rotary cycle

Describe the rotary-combustion engine

• The two trilobate (three-sided) rotors revolve in housing shaped in a fat figure-of-eight. The four sequences of the four-stroke cycle, which occur consequently in a piston engine, occur simultaneously in a rotary engine, producing power in a continuous stream.

• This engine uses compression alone, heating the compressed fuel/air mixture to the point where it explodes. A diesel engine’s fuel consumption is low in comparison with similarly sized piston engines, despite its heavier, reinforced moving parts and cylinder block.

What is the Wankel engine?

How does diesel engine work?

• This engine uses compression alone, heating the compressed fuel/air mixture to the point where it explodes. A diesel engine’s fuel consumption is low in comparison with similarly sized piston engines, despite its heavier, reinforced moving parts and cylinder block.
