Advantages of a Diesel Engine
The diesel engine is much more efficient and preferable as compared with gasoline engine due to the following reasons:
-
Modern diesel engines have overcome disadvantages of earlier models of higher noise and maintenance costs. They are now quiet and require less maintenance as compared with gas engines of similar size.
-
They are more rugged and reliable.
-
There is no sparking as the fuel auto-ignites. The absence of spark plugs or spark wires lowers maintenance costs.
-
Fuel cost per KiloWatt produced is thirty to fifty percent lower than that of gas engines.
-
An 1800 rpm water cooled diesel unit operates for 12,000 to 30,000 hours before any major maintenance is necessary. An 1800 rpm water cooled gas unit usually operates for 6000-10,000 hours before it needs servicing.
-
Gas units burn hotter than diesel units, and hence they have a significantly shorter life compared with diesel units.
你的關於汙染的評論脫離了效率這點,同樣開相同距離,柴油用量少於汽油,盡管其汙染產量比率比汽油高,但就這相同距離的排放,柴油未必比汽油高.
