What does engine model EQ6100-1 mean

EQ6 100-1 is a 135-horsepower gasoline engine of FAW Dongfeng.

y is generally used in the EQ6100 Dongfeng engine of the sea lion car 4y. 6 is a 6-cylinder and 100 is the cylinder diameter.

Dongfeng EQ140-1, engine model EQ6100-1 gasoline engine, gearbox is produced by Dongfeng Automobile Company itself, model 17D4-00030-B, front axle model is 30D-00005, rear axle model is 24D-000005. The vehicle was originally designed as a 5-ton class, and the carriage was longer than the 140-2.

Explain the meaning of the EQ6100Q engine

When the intake stops. The meaning of 6100q gasoline engine When the second cylinder is at the stop point under the intake, the experimental study of the EQ6100 Q gasoline engine has confirmed that the effective fuel consumption rate can be reduced under small and medium and low speeds, which has obvious effect and practicality.

EQ is a Dongfeng car brand, specifically: Dongfeng car, cylinder is in-line, 6-cylinder, four-stroke, cylinder diameter 100mm, water-cooled engine.

y is generally used in the EQ6100 Dongfeng engine of the sea lion car 4y. 6 is a 6-cylinder and 100 is the cylinder diameter.

Hello, EQ represents the car produced by FAW; 6 indicates that the engine is a 6-cylinder engine; 100 indicates that the cylinder diameter of the engine is 100mm; -1 indicates the factory's first deformed product.

The engine number consists of 4 parts, and the meaning of the representative is: the person in charge: including the product series code, the alternative symbol and the local and enterprise code. The manufacturer chooses the corresponding letters according to the needs, but it must be approved by the industry-standardized unit for the record.

What kind of development process has China's Dongfeng series military vehicles experienced?

The reason is actually very simple. Dongfeng military vehicles have become more and more powerful after experiencing the baptism of the national war and the test of the market, and now there are more than 300,000 oriental military vehicles serving national defense. Among the military vehicles used by active-duty troops, Dongfeng dominates one, accounting for 1/3 of the total.

Dongfeng Mengshi is China's first third-generation highly mobile military off-road vehicle, which has achieved the leapfrog development of troop equipment. It also has a positive role in promoting the independent research and development of Chinese automobiles.

China's military vehicles have experienced nearly a century of development, from nothing to something, from weak to strong. Looking back at the development history of this military vehicle, it is also the history of the country's continuous strengthening of comprehensive strength.

The function and working principle of the oil radiator

The oil radiator is arranged in the lubricating oil line, and its working principle is the same as that of the radiator, that is, it is used to cool the oil. Engine radiators are divided into air-cooled and water-cooled. The air-cooled oil radiator uses the oncoming wind during operation to dissipate heat, which is widely used in racing and supercharged engines with high heat load.

The function of the oil radiator is to forcibly cool the oil, prevent the excessive oil temperature from increasing the oil consumption, and also prevent the oxidation and deterioration of the oil. Oil radiator is also known as oil cooler. It is an oil cooling system applied to diesel engines. According to the cooling method, oil coolers can be divided into water cooling and air cooling.

A group of connectionsTo the oil road, let the oil flow through the heat exchanger, and the other group is connected to the coolant circulation pipe to transfer heat between the coolant and the oil. Cooling function: If the oil temperature is higher than the normal value, the oil will be too thin and the lubrication effect will be reduced.

What is the situation of crankshaft inversion when the Dongfeng EQ6100 engine is started?

When the crankshaft is reversed, when the engine starts, it will never reverse e. The reversal of the car is achieved by a set of gears in the gearbox. Imagine two gears woven together, one on the left and the other on the right. Customers sometimes wonder why the handle must be rotated by MEIA.

Dongfeng EQ6100- -1 engine, a steel ball is inlaid on the rim of the flywheel. When the steel ball is aligned with the engraved line on the flywheel shell, it means that the piston of 6 two cylinders is in the upper stop position.

The gap of the main bearing is too large, and the engine works under impact conditions such as explosion or overload, causing the crankshaft to vibrate excessively. ( 2) A few cylinders do not work or work unbalancedly. ( 3) The elasticity of each main bearing cover is inconsistent, so that the force of the crankshaft is uneven. ( 4) Coaxial deviation of the main bearing seat hole of the cylinder block.

During the start-up process, there will be crankshaft reversal phenomenon, intake manifold tering phenomenon, unstable idling, jitter, similar car lack of cylinder failure, speed, car can't run, car speed above 2500r is better, but the car has high fuel consumption, overweight emissions, exhaust pipe, exhaust pipe will smell of smoke. .

Loose.The phenomenon of the thrust stopping sheet falling off indicates that the end surface of the crankshaft main bearing has been seriously worn, and it will not help even if it is replaced with a new part. At this time, it should be removed for careful inspection and remedial measures should be taken.
