Some lorries have auxiliary equipment which requires power, but they don’t have a PTO or power take-off<\/a> that draws power from idling the main engine. Instead, they have a small auxiliary engine which can provide the power.<\/p>\n\n\n\n

Common applications for this include chillers on refrigerated trailers, the cranes on side-loader trailers and air compressors on vehicle service trucks. For this reason, it’s important that the engines are reliable otherwise downtime causes lost revenue.<\/p>\n\n\n\n

Auxiliary engines are serviced based on the number of hours they are run, compared to the lorry itself which will be serviced based on mileage.<\/p>\n\n\n\n

Auxiliary engines and connecting components need to be checked as part of the regular pre-start inspection. However, they can often be tucked away out of sight, so it’s important that if a new driver is using the lorry that they are shown where the engine is and how to stop and start it. Sometimes it’s right between the chassis rails, sometimes it’s behind a panel, sometimes you need to tip the cab, and sometimes it’s easily accessible near other components such as the toolbox.<\/p>\n\n\n\n

There may be information about what to check before operating the engine, and what type of fluids to use.<\/p>\n\n\n\n
