Natural gas engines are not as common as
gasoline and diesel engines because natural gas is not as easy to
transport. Gasoline and diesel engines are so popular because they
are a cheap and efficient way of providing portable power (the kind
of power you need in a car, truck, train etc). Natural gas engines
are mainly used for power production – combining the advantages
of natural gas (cheaper fuel) with the efficiencies and cost savings
of the internal combustion engine.
The design of a natural gas engine is almost
identical to that of the gasoline engine. Most natural gas engines
are spark ignited, and electronically controlled.
