Why do diesel engines not have spark plugs?
The higher the ratio, the more air is compressed, and more of the injected fuel is ignited during combustion. The result is a more powerful explosion and better performance. While compression ignition means that diesels don’t require spark plugs, they can come fitted with components called glow plugs.
Is it OK to drive with a bad glow plug?
During regular use, glow plugs will generally last between 90,000 and 110,000 miles. … Driving your truck with a burnt-out glow plug may not result in a malfunction all by itself, but if it’s left unaddressed for a long time, it can cause damage to the starter and the battery.
Are cold starts bad for diesels?
Myth #2: Diesel engines won’t start in the winter.
“Today’s technologies for cold-start are very effective,” Ciatti said. “Modern diesel engines start in cold weather with very little effort.” The problem is that diesel jells at low temperatures. Below about 40°F, certain hydrocarbons in diesel turn gelatinous.
