Diesel Generator Tech

Diesel generator valve drive is mainly composed of camshaft, timing gear, tappet, push rod, rocker arm and rocker shaft. The function of the valve train is to open and close the intake and exhaust valves at a specified time (gas timing) and order (fire order), and to ensure a certain degree of opening. 1. Camshaft and timing gear The camshaft is the main part of the valve train, and the process of opening and closing the valve is mainly controlled by it. The structure of the camshaft is as shown in Fig. 1. It is mainly equipped with a spiral gear or a confidence gear of each cylinder intake and exhaust cam, camshaft journal and drive attachment (such as oil pump). The mutual positions of the cams on the camshaft are arranged in the order of firing specified by the engine. The firing order of the engine can be judged based on the relative positions of the cams and the direction of rotation of the camshaft. In order to ensure that the fuel injection of the diesel engine is reli...

1. Fuel consumption rate: diesel generators of different brands have different fuel consumption rates and different fuel consumption. 2. The size of the electric load: the load is large and the fuel consumption is larger. On the contrary, the load is smaller and the relative fuel consumption is smaller. In order to facilitate the understanding of the approximate fuel consumption of the generator set and calculate the use cost of the generator set, we will estimate the approximate fuel consumption of the generator set under full load (30kw-500kw) for your reference. The list is as follows: 30kw fuel consumption = 6.3 kg (kg) = 7.8 liters (L) 45kw fuel consumption = 9.45 kg (kg) = 11.84 liters (L) 50kw fuel consumption = 10.5 kg (kg) = 13.1 liters (L) 75kw fuel consumption = 15.7 kg (kg) = 19.7 liters (L) 100kw fuel consumption = 21 kg (kg) = 26.25 liters (L) 150kw fuel consumption = 31.5 kg (kg) = 39.4 liters (L) 200kw fuel consumption = 40 kg (kg) = 50 liters...

I Long-lasting coolant addition Use premixed or concentrated coolant only for Perkins products. Perkins extenders can only be used with long-life coolants. Mix long-life coolant with other products to reduce the life of long-life coolant. The failure to do so will reduce the life of the cooling system components unless proper remedial action is taken. Perkins Low Noise Diesel Generator Set To maintain the correct balance between coolant and additives, the recommended concentration of long-life coolant (ELC) must be maintained. Lowering the proportion of the coolant also reduces the proportion of the additive. This will reduce the ability of the coolant protection system to resist pitting, cavitation, erosion and deposits. Note: Be careful not to use conventional coolant to supplement the cooling system filled with long-life coolant (ELC). do not use the standard supplemental coolant additive (SCA). The ELC extender is only used in the RLC cooling system. Do not us...

On December 21, Guangxi Yuchai Machinery Co., Ltd. has once again set up its significant milestone of the cooperation project with Germany’s MTU. The 100th high-end high-powered engine S4000 of MTU Yuchai Anteyou Power Co., Ltd. (hereinafter referred to as “MTU Yuchai Anteyou”), a joint venture of the two sides, rolled off the assembly line. The production from the first to the 100th signifies that MTU Yuchai Anteyou has possessed the capability of batch production, giving it a chance to be closer to the goal of producing 1,500 engines per year. Yan Ping, Chairman of Yuchai Machinery, together with Jin Shixin, Vice President of Strategic Customers of Rolls-Royce Power Systems AG in Greater China and CEO of MTU Yuchai Anteyou, unveiled the engine. On April 9 this year, MTU Yuchai Anteyou celebrated the birth of S4000 engine, its first high-end high-powered engine. In about eight months, MTU Yuchai Anteyou has adopted the same production line with MTU, and followed the same produ...

1. Generator overheating (1) The generator does not operate in accordance with the specified technical conditions, such as too high stator voltage, iron loss increases; if the load current is too large, the copper loss of the stator winding increases; if the frequency is too low, the cooling fan speed becomes slow, affecting the heat dissipation of generator; the power factor is too low, so that the rotor excitation current increases, resulting in the rotor heating. Check whether the indication of monitoring instrument is normal. If it is abnormal, necessary adjustment and treatment must be carried out to operate the generator in accordance with the specified technical conditions. 2. The generator neutral line has abnormal voltage to the ground. (1) Under normal circumstances, due to the influence of high harmonics or manufacturing process, the air gap under each magnetic pole is uneven and the magnetic potential is unequal, and the voltage is low. If the voltage is ...

The structure of the brushless AC synchronous generator is divided into two parts, a stationary part and a rotating part. The stationary part is called a stator, and includes a base, a stator core, a stator winding, an end cover, a bearing cover, and a stator of an AC exciter. Stator It consists of a base, a stator core and a stator winding. The stator core and the stator winding are part of the induced potential and current, which is also called the armature. 1. Base: The overall support of the generator, used to fix the armature and the front and rear end caps together to support the rotor. There are generally outlet boxes on the base, located on the upper part of the base, and only on the right side (from the extended end of the shaft). A wiring board is installed in the outlet box to draw an alternating current or the like. 2. Stator core: part of the stator iron core generator magnetic circuit. In order to reduce the eddy current loss, the core is formed by lam...

1. Strict temperature requirements The number on the diesel generator represents its frost resistance. It is generally required to use diesel of -10 or even -30 in winter, and it is enough to use diesel No. 0 in summer. Cold filter points and condensation points are the two main indicators used to measure diesel antifreeze performance. Among them, the unit's condensation point refers to the lowest temperature at which diesel can maintain fluidity under low temperature conditions. This indicator will mainly affect the storage and transportation of diesel; the cold filter point means that diesel does not pass through the engine fuel supply system. The lowest temperature that will cause the filter to clog, and the fuel supply index of the diesel engine will be directly affected by it. 2. Strategy to ensure unit startup temperature The temperature of the diesel oil should not be lower than 4 ° C. In other words, it is necessary to ensure that the ambient temperature of th...

On November 23, the JAC box van truck HFC 5161 equipped with YC4S160-50 began testing in the La Oroya area of Peru. The La Oroya area is 4,000-5,000 meters above sea level. Starting from Lima, the capital of Peru, the truck traveled 150 kilometers straight from an altitude of 50 meters to an altitude of 5,000 meters. Along the way, there are high hills and steep slopes with thin air, which is the perfect natural test field to check the adaptability and power performance of vehicles and engines in the plateau. Since the Andes Mountains with the same altitude run through the entire Peruvian territory from north to south, every new car model introduced to this place must pass the plateau test to prepare for the subsequent sales across the country. Supported by the products of YC4S Euro V, this is the first batch of JAC medium and heavy trucks to enter the Peruvian market since 2014, which is also the new model developed jointly by Yuchai and JAC to meet the needs of different custom...
