Blow-by, as it is often called, is the result of combustion material from the combustion chamber "blowing" past the piston rings and into the crankcase. These blow-by gases, if not ventilated, inevitably condense and combine with the oil vapor present in the crankcase, forming oil sludge.
The way to test the flash point of the oil is to manually take a sample and use a testing kit. When the fuel leaks into the lube oil the chemical makeup is different than the normal lube oil. Another way to test for crankcase dilution is to use a SAW to test the concentration of fuel oil in the crankcase oil. [5] SAW stands for surface acoustic ...
Bag valve mask. Part 1 is the flexible mask to seal over the patients face, part 2 has a filter and valve to prevent backflow into the bag (prevents patient deprivation and bag contamination) and part 3 is the soft bag element which is squeezed to expel air to the patient
EGR valve the top of box on top of the inlet manifold of a Saab H engine in a 1987 Saab 90. In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO x) emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. [1]
Instrumentation controls the operation of process columns. Instrumentation is used to monitor and control the process plant in the oil, gas and petrochemical industries. . Instrumentation ensures that the plant operates within defined parameters to produce materials of consistent quality and within the required specifica
When implemented in a locomotive, the ECU may also be incorporated into the Locomotive Control Unit (LCU), which performs a variety of functions, such as wheel-slip control, "phone home" for incident reporting and scheduling of delivery of service parts, etc. EMD's LCU is often GPS-assisted, and maintenance personnel can effectively monitor the performance of perhaps thousands of locomotives ...
Actually, just the converse is true: with diesel or gasoline/petrol as fuel, piston-ring blowby causes dilution of crankcase lubrication, reducing lubricity/protection, increasing wear, with a cumulative effect of poorer efficiency and increased damage over time.
