DIESEL-FIRED COOLANT HEATERS: A PRELIMINARY EVALUATION ON CONVENTIONAL TRANSSIT BUSES FOR THE TOWN OF MARKHAM

Outdoor storage of transit buses during the winter months is being looked at as a possible way of reducing capital costs for transit operators. However, there are problems involved, particularly in starting the engine on cold days, and in ensuring a comfortable temperature for passengers during the first minutes of revenue service. Six identical Orion 40-foot buses were used to evaluate four competing diesel-fired coolant heaters in January and February 1991. These units, which consume diesel fuel from the vehicle's fuel tank to heat the engine coolant, were expected to preheat the engine adequately and when needed and to warm the passenger compartment and keep it warm when the bus is on its route. This report provides the results of the tests.
