Diesel pollution control system

Abstract

A pollution control system for diesel engines includes a PCV valve and an oil filter positioned together in a canister. An open/closed state of the PCV is regulated by a controller, preferably wirelessly, responsive to sensed blow-by conditions, including pressure, temperature, composition, and/or flow rate. The controller also wirelessly receives measurements from an in-line blow-by gas sensor for regulating the PCV valve. The oil filter cleans particulate matter out of the blow-by gas, and condenses oil to return to the engine. The controller regulates the amount of blow-by gas vented through the system.

What is claimed is: 
     
         1 . A diesel pollution control system, comprising:
 a PCV valve having an inlet and an outlet adapted to vent blow-by gas from a crankcase of a diesel combustion engine;   an oil separator having an inlet and top and bottom outlets, wherein the inlet is fluidly coupled to the crankcase, the bottom outlet is fluidly coupled to a return port on the crankcase and the top outlet is fluidly coupled to the PCV valve;   a blow-by line fluidly connecting the outlet of the PCV valve to an intake manifold on the diesel combustion engine; and   a controller connected to the PCV valve for selectively modulating an open/closed state of the PCV valve responsive to real time blow-by conditions so as to regulate vacuum pressure in the engine and adjustably increase or decrease a fluid flow rate of blow-by gas from the crankcase.   
     
     
         2 . The system of  claim 1 , wherein the connection of the controller to the PCV valve is wireless. 
     
     
         3 . The system of  claim 1 , further comprising a blow-by sensor connected to the controller and in-line with one of the inlet on the oil separator, the top outlet on the oil separator, or the blow-by line for measuring real-time blow-by conditions, including blow-by pressure, blow-by temperature, blow-by composition, or blow-by fluid flow-rate. 
     
     
         4 . The system of  claim 3 , wherein the connection of the controller to the blow-by sensor is wireless. 
     
     
         5 . The system of  claim 3 , wherein the controller and blow-by sensor utilize superconductors in place of wiring and integrated circuit chipsets. 
     
     
         6 . The system of  claim 2  or  4 , wherein the wireless connection is via Wi-Fi, radio, ultrasonic, infrared, or SMS. 
     
     
         7 . The system of any of  claims 1 - 5 , wherein the PCV valve regulates fluid flow between its inlet and outlet utilizing a solenoid mechanism, an electromagnetic orifice control mechanism, an inductive field orifice control mechanism, or a fiber optic orifice control mechanism. 
     
     
         8 . The system of  claim 3 , wherein the oil separator comprises a plurality of permeable mesh layers having different gauges adapted to separate the blow-by gas into fuel vapors and oil droplets. 
     
     
         9 . The system of  claim 8 , wherein the plurality of permeable mesh layers are a metal or metal alloy comprising steel, stainless steel, aluminum, copper, brass or bronze. 
     
     
         10 . The system of  claim 3 , further comprising an oil filter disposed between and fluidly coupled with the bottom outlet of the oil separator and the return port on the crankcase. 
     
     
         11 . The system of  claim 10 , further comprising an oil accumulator disposed between and fluidly coupled with the oil filter and the return port on the crankcase. 
     
     
         12 . The system of  claim 3 , wherein the blow-by line is fluidly coupled to a main fuel line into the diesel combustion engine. 
     
     
         13 . A process for controlling pollution in a diesel combustion engine, comprising the steps of:
 venting blow-by gasses from a crankcase of a diesel combustion engine via vacuum pressure using a PCV valve;   sensing real-time blow-by gas conditions, including blow-by pressure, blow-by temperature, blow-by composition, or blow-by fluid flow-rate;   modulating an open/closed state of the PCV valve responsive to the real-time blow-by gas conditions;   adjusting the blow-by fluid flow-rate of blow-by gas from the crankcase;   separating the blow-by gasses into liquid oil and fuel vapors;   returning the liquid oil to the crankcase; and   recycling the fuel vapors to an intake manifold of the diesel combustion engine.   
     
     
         14 . The process of  claim 13 , further comprising the step of filtering the liquid oil prior to the returning step. 
     
     
         15 . The process of  claim 13 , further comprising the step of mixing the fuel vapors with an alternative fuel prior to the recycling step.
