Murphy oil pressure gauges with switches that activate on low pressure. Oil pressure is an important factor in the longevity of most internal combustion engines. [1] With a forced lubrication system (invented by Frederick Lanchester), oil is picked up by a positive displacement oil pump and forced through oil galleries (passageways) into bearings, such as the main bearings, big end bearings ...
The Skyactiv-G [7] is a family of direct injection petrol engines. The engine compression ratio is 14:1, except in the U.S. market where it is 13:1 so the engine can operate on regular instead of premium gasoline; the lower compression ratio reduces torque and fuel economy by 3 to 5 percent. [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.
Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication.

The Mazda CX-5 is a compact crossover SUV [1] produced by Mazda since 2012. [2] A successor to both the Tribute and the slightly larger CX-7, [3] [4] it is Mazda's first model to feature the "Kodo" design language and the first model to be fully developed with a range of technologies branded as Skyactiv, including a rigid, lightweight platform combined with a series of engines and ...
The engine computer stores optimum air fuel ratios for all engine-operating conditions—from lean (for normal operation) to richest (for heavy acceleration) and all points in between. Full-range oxygen sensors (used for the first time) provide essential information that allows the computers to properly regulate fuel delivery.
The Mazda Y6 engine (called 1.6 MZ-CD or 1.6 CiTD) is a rebadged PSA DV6 engine, produced in the PSA engine plant in Trémery and the Ford engine plant in Dagenham. This 1.6 L (1,560 cc) DOHC 16-valve turbo diesel engine has a bore and stroke of 75 mm × 88.3 mm (2.95 in × 3.48 in), and a compression ratio of 18.3:1.
Dieseling or engine run-on is a condition that can occur in spark-plug-ignited, gasoline-powered internal combustion engines, whereby the engine keeps running for a short period after being turned off, drawing fuel through the carburetor, into the engine and igniting it without a spark.
