Roughly 72 liters (19 U.S. gal) of gasoline is derived from a 160-liter (42 U.S. gal) barrel of crude oil. [6] Material separated from crude oil via distillation, called virgin or straight-run gasoline, does not meet specifications for modern engines (particularly the octane rating; see below), but can be pooled to the gasoline blend.
A diesel cycle engine can be as much as 40% to 50% efficient at converting fuel into work, [2] where a typical automotive gasoline engine's efficiency is about 25% to 30%. [3] [4] In general, an engine is designed to run on a single fuel source and substituting one fuel for another may affect the thermal efficiency.
The GM L3B engine is a turbocharged four-cylinder gasoline engine designed by General Motors. It is an undersquare aluminum DOHC inline-four displacing 2.7 liters (165 cid) and tuned for strong low-end torque.
The engine was introduced in 1992 as the L10G before being replaced by the L Gas Plus in 2001 until it became the ISL G in collaboration with Westport Innovations in 2008, now based on the C-series engine architecture. The ISL engines were manufactured at plants in Rocky Mount, North Carolina and Darlington, England. [3]
This new engine family would provide better gas economy than the 350, share its basic architecture and many parts with the 350 (thus reducing production costs), and provide customers with more horsepower and torque than Chevrolet's 1970s-era inline 6 and V6 engines.
The main petroleum component used in blending avgas is alkylate, which is a mixture of various isooctanes. Some refineries also use reformate.All grades of avgas that meet CAN 2–3 [further explanation needed], 25-M82 [further explanation needed] have a density of 6.01 pounds per US gallon (720 g/L) at 15 °C (59 °F).
Engines that use gases for fuel are called gas engines and those that use liquid hydrocarbons are called oil engines; ... in miles per gallon or in liters per 100 ...
Today, motor oil in the US is generally sold in bottles of one U.S. quart (950 mL) and on a rarity in one-liter (33.8 U.S. fl oz) as well as in larger plastic containers ranging from approximately 4.4 to 5 liters (4.6 to 5.3 U.S. qt) due to most small to mid-size engines requiring around 3.6 to 5.2 liters (3.8 to 5.5 U.S. qt) of engine oil.
