internal combustion-engined

Worldwide, there are an estimated 400,000 motor vehicles burning gaseous fuels. There are over 250,000 natural gas powered vehicles in Italy alone, and New Zealand has a program underway to convert 150,000 to natural gas by 1983. This is a very small fraction of the internal combustion-engined vehicles in use.

Internal combustion–engined vehicles thus “fit” better with advanced capitalist economies than steam engines.

Hybrid systems differ from previous automotive designs in that they contain battery packs, which can provide potentially lethal electrical shocks and which may, if compromised, provide a unique set of potential ignition sources, as compared with internal combustion-engined vehicles.
