marine engine water temp gauge

• 2022-10-09

Our company engine water temp gauge can be used on auto or marine , customer can choose the different colors , size and scale. We have marine instrument panel , also can sell the gauge separately . The parameters displayed by the temperature gauge are provided by the engine ECU through the J939 data bus. The data is first provided to the J939 multi-function meter and can be displayed on the meter, and then sent to the instrument assembly bus by the multi-function meter for display. The indication scale is divided into nine grades, 40~120 ℃, and the indication resolution is 10 ℃.

Marine diesel engine has high thermal efficiency, good economy, easy starting, and great adaptability to all kinds of ships. It was soon used as ship propulsion power after its appearance. By the 1950s, diesel engines had almost completely replaced steam engines in newly built ships. Marine diesel engine has been the main power of civil ships, small and medium-sized ships and conventional submarines. Marine diesel engine can be divided into main engine and auxiliary engine according to its role in the ship. The main engine is used as the propulsion power of the ship, and the auxiliary engine is used to drive the generator, air compressor or water pump. Marine diesel engines are generally divided into high-speed, medium speed and low-speed diesel engines. Therefore, it is necessary to know the engine temperature at all times, and it is necessary to install the marine engine water temp gauge.

What is the normal water temperature of marine engine? The water temperature of any diesel engine is basically within 95 ° C, 80 ° C to 90 ° C is appropriate, and the temperature above 95 ° C is high. The low temperature water shall be controlled between 38-45 ℃ and the high temperature water shall be controlled between 90-97 ℃. The water temperature is too high (early combustion, spontaneous combustion, thermal tightening), which means that the engine can hear the cylinder knock when accelerating. The ignition time is too early (deflagration). The injection time is 14-18 degrees before TDC (diesel engine). Excessive wear of engine crank and connecting rod mechanism will cause cylinder knock. Engine knock sensor and knock control system failure. If your water temperature is low, check the thermostat. When the engine temperature is low, rich mixture is required to maintain stable operation.
