Question

which of the following is a correct statement regarding engine starting aids?
diesel engines often use glow plugs.
engine block heaters remain on while the machine is moving.
gasoline engines always require starting fluid in cold weather.
ether is often combined with other chemical starting aids.

Explanation:

• Glow plugs are a standard starting aid for diesel engines, as they heat the combustion chamber to help ignite diesel fuel, especially in cold weather.
• Engine block heaters are only used before starting the engine, not while the machine is operating.
• Gasoline engines do not always require starting fluid in cold weather; many use other methods like improved ignition systems, so this statement is incorrect.
• Ether is typically used alone as a starting aid, not combined with other chemical aids, so this statement is wrong.

Answer:

Diesel engines often use glow plugs.
