The oil is dyed blue to make it easier to recognize in the gasoline. It appears black in this bottle because it is not diluted. Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a special type of motor oil intended for use in crankcase compression two-stroke engines, typical of small gasoline-powered ...
Amount of two-stroke oil injected by the pump depends on the throttle position. A cable from the throttle is connected to the oil pump indicating throttle's position. A tube ensures flow of oil from the reservoir to the oil pump. This system is commonly used for motorcycles as it eliminates the need of pre-mixing fuel and two-stroke oil.
In crankcase scavenged 2-stroke engines, exhaust and intake are performed mostly simultaneously and with the combustion chamber at its maximum volume. The main advantage of 2-stroke engines of this type is mechanical simplicity and a higher power-to-weight ratio than their 4-stroke counterparts. Despite having twice as many power strokes per ...
API TC is a certification for two-stroke oils, awarded by the American Petroleum Institute. It is given after the product passes through stringent tests that determine the level of detergent performance, dispersion, and anti-oxidation. It is the only remaining, not revoked classification of the API Two-Cycle motor oil specifications (TA, TB, TC ...
Silkolene 2-stroke oil was directly injected into the inlet tracts and onto the main roller bearings. The oil that entered the combustion chamber lubricated the rotor tips and was then total-loss, but the oil that fed the bearings became a mist within the rotor-cooling air, and around 30% [ 2 ] of that oil was recovered and returned to the ...

Since naturally aspirated four-stroke engines must perform pumping work to suck the charge into the cylinder, and to remove the exhaust from the cylinder, IMEP may be split into the high-pressure, gross mean effective pressure (GMEP, ) and the pumping mean effective pressure (PMEP, ). In naturally aspirated engines, PMEP is negative, and in ...
The Oklahoma Geological Survey in 2015 published a map that displays gas wells with greater than 20 MCFG per barrel of oil. [2] They go on to display oil wells with GOR of less than 5 MCFG/BBL and oil and gas wells between these limits. The EPA's 2016 Information Collection Request for Oil and Gas Facilities (EPA ICR No. 2548.01, OMB Control No ...
