Special Technology Used in 16V165RQ Gas Engine 1. Shunt cycle cooling technology The 16V165RQ gas engine adopts the TE cooling cycle system of 396 diesel engine, which adopts a new concept of shunt circulating cooling structure, one of which cooling circuit is moderately cooled to the pressurized air according to the changing state of power. Therefore, the cooling water discharged from the engine is divided into two cycles of "high temperature cycle" and "low temperature cycle". About 2/3 cooling water goes back to the intake side of the engine pump directly through the high temperature cycle, and the rest is introduced into the low temperature loop controlled by a temperature regulator. In the empty and low load conditions, the regulator controls the high temperature cooling water from the diesel engine to bypass the circulating cooler and directly into the supercharged air cooler through the bypass line. And in which the pressurized air is heated to

Repair Instructions of Volvo Engine Spare Parts Magnetically controlled proportional valve (MPROP) A magnetically controlled proportional valve (MPROP) controls the high pressure pump to ensure that the correct fuel pressure (rail pressure) is retained despite varying engine speed and loading. The input signal to the valve is a PWM signal whose pulse width is controlled by the engine control module. When the current through the valve is changed, this affects the fuel flow, which results in changed rail pressure. Water in fuel switch, secondary fuel filter A switch is located in the water trap under the fuel filter. Its task is to detect whether there is water in the fuel. The switch senses the resistance between two pins, wich are in contact with the fuel. When there is no water in the fuel, the resistance is very high. If there is any water in the fuel, the resistance falls. Switch, coolant level The task of the switch is to discover whether the coola
