Abstract
The aim was to clarify the extent of the eventual reduction of fuel consumption and exhaust emission which could be achieved by previously heating the car`s engine with a car-engine preheater. Costs and operational consequences were also investigated. Tests were made on electric, petroleum and diesel-driven heaters. With regard to a gasoline-driven car and a cold startup, (- and + 5 degrees centigrade) the reduction of unburned hydrocarbons and carbon monoxide emissions was ca. 50% in the case of an electric preheater and 80% where a petrol-driven preheater was used, but there was an increase of 75-125% of nitrogen oxides emission. In the case of the diesel-driven vehicle and a 5 degree centigrade cold start there was an increase of hydrocarbon emission of 20% and a fall in nitrogen oxides emission by 5% where an electric heater was used. Where diesel-driven preheaters were used, hydrocarbon emission increase was at the rate of 30% and decrease of nitrogen oxides emission of 10%. Carbon monoxide emission was extremely low and showed little change in either case. The change in HC and NO{sub x} emissions as a function of the start temperature is the opposite of that which is the case of the

It is concluded that it is of little or no advantage to use engine preheaters in diesel-driven vehicles. It is also concluded that cost and operational costs of using engine preheaters can not be covered by money saved by lowered fuel consumption. Yet a car-engine preheater could be a useful purchase for most car owners, as a small extra expence can be weighed up against start-up stability and speedier heating of the car. (AB).}
