Engine oil system

摘要

An engine oil system according to the disclosure comprises an oil pump connected to an oil sump, an oil cooler connected to the oil pump and an oil filter. The oil filter is connected to an engine. The engine oil system further comprises a first by-pass conduit connected to the oil pump and which is arranged to be connected to a component of the engine oil system other than the oil cooler. The first by-pass conduit comprises a first by-pass valve, wherein, in a first mode, the first by-pass valve is in an open state allowing oil to by-pass the oil cooler, and wherein, in a second mode, the first by-pass valve is in a closed state directing the oil through the oil cooler. The disclosure also relates to a vehicle comprising an engine oil system.

主权项

1. An engine oil system comprising:
an engine; an oil pump connected to an oil sump; an oil filter connected to the engine; an oil cooler connected to the oil pump and the oil filter; a first by-pass conduit connected to the oil pump and the oil filter, the first by-pass conduit comprising a first by-pass valve, wherein, in a first mode, the first by-pass valve is configured to be in an open state for allowing oil to by-pass the oil cooler and pass through the oil filter before flowing to the engine, and wherein, in a second mode, the first by-pass valve is configured to be in a closed state for causing the oil to be directed through the oil cooler; anda second by-pass conduit comprising a second by-pass valve, the second by-pass conduit being connected to the oil pump and to the engine, wherein the second by-pass valve in a third mode is configured to be in an open state for allowing oil to by-pass the oil cooler, and wherein the second by-pass valve in a fourth mode is configured to be in a closed state for causing the oil to be directed through the oil cooler;
wherein the first by-pass conduit is configured to allow the oil to by-pass the oil cooler without passing through the second by-pass valve, and the second by-pass conduit is configured to allow the oil to by-pass the oil cooler without passing through the first by-pass valve, and wherein at least one of the first and second by-pass valves is configured to be controlled by a thermostat or an electric actuator.
