Which of the following statements describes the operating characteristics of a precombustion chamber?

Question

Accepted Answer

When fuel oil is injected into the precombustion chamber, it does not need to be as finely atomized as the fuel oil in diesel engines having direct injection.

Answer

When operating correctly, combustion should not occur in the precombustion chamber.

Answer

Engines which are designed with precombustion chambers are more likely to suffer blocked nozzle holes, due to fuel oil impurities, than engines designed with direct injection.

Answer

Engines with precombustion chambers, which do not have an increased compression ratio, are not as difficult to start when cold, as engines with direct injection.
