- (D) black smoke will be produced
- (E) lot of fuel will remain unburnt
- (A) the shape and layout of the piston crown, the inlet port, and the valve produce the turbulent effect of fuel mixture
- (B) fuel is injected into an auxiliary chamber that is separated from the cylinder by an orifice or throat
- (C) only a part of air charge is contained in an auxiliary chamber in which the fuel starts to burn with insufficient air which due to explosion tendency mixes thoroughly into main cylinder charge
- (D) there are no valves
- (E) fuel is partly burnt by spark
