Oil system for diesel engines that operate in cold environments |
摘要 |
An aftermarket modification for diesel engines that operate in cold environments particularly those using an air-to-liquid oil cooler. Engine oil can be routed to a filter and if the oil has not reached the desired operating temperature, a bypass module having a temperature element directs the oil past the cooler to return to the engine. Once the desired oil temperature is reached, the thermostatic element closes to direct oil through the cooler. A pressure bypass element can be incorporated into the bypass module. If the pressure differential between the inlet and outlet of the cooler exceeds a set point, a portion of the oil bypasses the cooler. |

1. A method of modifying a diesel engine for cold weather operation, said engine having a manifold having engine oil and return oil ports, said method comprising:
connecting the engine oil port to a filter having an outlet; connecting the filter outlet to a tee fitting; directing one branch of the tee to an oil cooler; connecting the other branch of the tee to a bypass module at a first port; connecting the outlet of the cooler to a second port of the bypass module, said second port communicating via a passageway with a return oil port; connecting the return oil port to the engine return oil port; and installing a thermostatic element which operates to direct oil to the return port if the oil temperature is below a preset level and which, when closed, directs oil to the cooler before being directed to the return port. |
