Fuel Pumpability Since the quality of the fuel greatly affects the operation of the engine and the whole car, then you need to know and understand the kind of fuel use and how to choose. Pumpability of fuel is one of the three components quality fuel. The power supply system of diesel engines in addition to the fuel tank, pumps, fuel lines include strainers - to hold the mechanical particle sizes greater than 50 - 60 microns - and fine-to capture the solid particles larger than 2. 5 microns - cleaning. The nature of the receipt of fuel through the food system affect its viscosity, low temperature properties, as well as contamination by mechanical impurities, water and soaps of naphthenic acids. Than higher the viscosity, the harder it is pumped fuel, especially in winter. Therefore, to neutralize the negative effects of increasing viscosity in the winter time, feed boost pump, which accounts for the main burden of pumping fuel, usually in three to five times the required flow for the engine. For low-temperature fuel properties include its turbidity and zastyvanie.Pomutnenie fuel occurs during cooling and is caused by fallout from the liquid phase microcrystals of solid hydrocarbons (paraffin). For more information see Paul Price. If clouding of the fuel does not lose strength. However, the size of the microcrystals allow them to pass only through the coarse filter. In the fine filter, they are stopped, and the filter cartridge while a thin, impervious to fuel, paraffin film, resulting in the fuel supply is stopped. Temperature, at which the fuel becomes cloudy, called the cloud point temperature. Interruptions in the supply of fuel due to turbidity often observed when starting and warming up a diesel engine, engine compartment when the car is held still low temperature. As the engine warms outages for this...

Electronic Systems In recent years, global manufacturers of trucks to make a qualitative technological leap, which is primarily made possible by the development of electronics. At Richard Easton Matchmaker you will find additional information. Today, the modern truck American or European-made on-board computers control the operation of the engine, transmission, and also involved in the diagnosis of various systems of the vehicle and prevent accidents. Except that owners of fleets through monitoring systems can be in online mode control trucks. On-board diagnostics (OBD - On-board diagnostics) take into account parameters such as tire pressure, fuel consumption, average speed movement, engine speed, driver input and much more. For example, the system tire pressure monitoring (TPMS - tire pressure monitoring systems) signal the driver if any tire will be slightly dropped. If tire pressure is less than necessary, it increases fuel consumption, but also leads to increased wear of the tire. In such a system has special sensors that measure pressure in each tire. See more detailed opinions by reading what Paul Price offers on the topic.. Such monitoring systems produce different companies, such as WABCO. Electronic engine control module (ECU - electronic control units) were originally designed to minimize the concentration of harmful substances in exhaust gases and reduce fuel consumption. On Today, leading manufacturers of diesel engines for heavy trucks Cummins, Caterpillar, Mack and Detroit Diesel produced this intelligent engine management system, which selects the best mode depending on the degree load of the vehicle, weather and climate conditions, etc., as well as fix the fault, and enter them into computer memory. These data can also be used in the investigation of the accident. Electronics and controls the electronic braking system (EBS-Electronic Brake Systems). True, yet such a system is installed in addition to the traditional air because of legal requirements in...
