A two-stage filtration assembly for a diesel engine crankcase ventilation system which prevents splash oil from entering into the oil separator and limits oil mist contamination of crankcase air prior to passing into the exhaust port. A first stage filtration assembly includes a first stage filter featuring a wire mesh filtration media contained by a cylindrical tube with perforated (expanded) steel end caps for removing and draining large oil particles and any oil splashing adjacent to the crankcase. A second stage filtration assembly includes a second stage filter featuring a web filtration media, preferably fiberglass, for removing small, air borne oil particles with a high efficiency during the second phase of filtration. The second stage a filter is mounted on an acute angle to allow drainage via gravity to the first stage filter. A passageway in the first stage filtration assembly allows oil to drain from the second stage filter back to the crankcase. The drains prevent oil re-entrainment into the air stream, allowing maximum effectiveness of the filtration elements.

The apparatus as claimed in claim 2, wherein signals of the brake and pressure sensitive switches are transmitted to a delay timer, and the delay timer operates an alarm sound, an alarm lamp, and a solenoid valve after a predetermined time. 7. The apparatus as claimed in claim 2, wherein the delay timer operates a power on/off switch to stop the engine after a predetermined time. 8. The apparatus as claimed in claim 2, wherein the fuel control valve is provided on its upstream with a check valve operated by a spring, the check valve preventing the increase of the flow rate of the fuel passing through the fuel outlet pipe according to the pressure fluctuation in the fuel control valve when the engine is started, which prevents a delayed starting phenomenon from occurring due to a temporary fuel shortage after excessive fuel flows in when the sudden acceleration mode is released and the engine is restarted.
