The same engine at sea level will achieve that same 50 kPa (7.25 psi, 14.7 inHG) of manifold pressure at less than (before reaching) WOT due to the higher barometric pressure. The engine requires the same mass of fuel in both conditions because the mass of air entering the cylinders is the same.
The BMW B38 is a 1.2 and 1.5 L (1,198 and 1,499 cc) turbocharged straight-three DOHC petrol engine, which replaced the straight-four BMW N13.Production started in 2013. It is part of a modular BMW engine family, of straight-three (B38), straight-four and straight-six alloy block and head petrol engines, [1] which use a displacement of 400 cc (24.4 cu in) per cylinder in the 1.2 and 500 cc (30. ...
Manifold vacuum, or engine vacuum in a petrol engine is the difference in air pressure between the engine's intake manifold and Earth's atmosphere. Manifold vacuum is an effect of a piston's movement on the induction stroke and the airflow through a throttle in the intervening carburetor or throttle body leading to the intake manifold. It is a ...
As of 2010, the L15A7 (i-VTEC) is a class legal engine choice for SCCA sanctioned Formula F competition, joining the 1.6L Ford Kent engine. [ 1 ] In 2016 Honda introduced the L15B (DOHC-VTC-TURBO-VTEC) engine as part of their continuing global earth dreams strategy for lower emissions and higher fuel economy for a range of their cars, available ...

Maximum output: 67 kW (90 hp; 91 PS) Maximum torque: 121 N⋅m (89 lb⋅ft) Applications: Toyota Yaris Cross Hybrid (NYC200, 2023–present) [8]
Indications of low oil pressure may be that the warning light is on, a low pressure reading on the gauge, or clattering/clinking noises from the engine. Low oil pressure is a problem that must be addressed immediately to prevent serious damage. The leading cause of low oil pressure in an engine is wear on the engine's vital parts.
An illustration of several key components in a typical four-stroke engine. For a four-stroke engine, key parts of the engine include the crankshaft (purple), connecting rod (orange), one or more camshafts (red and blue), and valves. For a two-stroke engine, there may simply be an exhaust outlet and fuel inlet instead of a valve system.
The original XK had an 1,130 cc displacement; later the 1.3 liter XL engine appeared and then the 1.5 liter XR series which was developed specifically for the 305. There were also diesel engines developed; the 1,255 cc XLD and the 1,357 cc XL4D. In 1979 the XID appeared, with 1,548 cc this version shared many parts with the XR petrol engine.
