Placing the oil pump low-down uses a near-vertical drive shaft, driven by helical skew gears from the camshaft. Some engines, such as the Fiat Twin Cam engine of 1964, began as OHV engines with an oil pump driven from a conventional camshaft in the cylinder block. When the twin overhead cam engine was developed, the previous oil pump ...
The most common causes are accidents with grease guns, paint sprayers, and pressure washers, but working on diesel and gasoline engine fuel injection systems as well as pinhole leaks in pressurized hydraulic lines can also cause this injury.
Low quality diesel fuel was a common problem at the time and most diesels were thus equipped to keep the injector pumps from corroding. Many owners tried to solve this by adding anhydrous alcohol , a common trick to deal with water in fuel, but this instead dissolved fuel pump seals and other parts.
Oil pump may refer to: Hydraulic pump, which pressurizes hydraulic fluid in a hydraulic system; Oil pump (internal combustion engine), a part of the lubrication system that pressurizes motor oil for distribution around the engine; Pumpjack, often used to pump oil out of wells; Submersible pump, often used to pump oil out of wells
Pre-heating of certain housing sections with exhaust gas improved performance and fuel economy, also reducing wear and emissions. [65] The boundary layer shields and the oil film act as thermal insulation, leading to a low temperature of the lubricating film (approximate maximum 200 °C or 390 °F on a water-cooled Wankel engine).
[28] [29] This design, called a hot-bulb engine used a 'jerk pump' to dispense fuel oil at high pressure to an injector. Another development in early diesel engines was the pre-combustion chamber, which was invented in 1919 by Prosper l'Orange [30] to avoid the drawbacks of air-blast injection systems
Quality issues included the frequent failure of gearboxes and water pumps, poor engine cooling that often resulted in motors overheating, and generally poor production quality and panel fit. As a result, the Imp never sold as well as the Rootes Group had expected, and never even came close to the sales of the Mini.
