What should Iveco diesel vehicles do if they are not easy to strike fire in winter?

1. Due to the recent low gas temperature, rapid heat dissipation and low crankshaft speed, the temperature and pressure in the cylinder at the end of the compression stroke are too low to reach the auto-ignition temperature of the fuel. Generally, diesel engines require that the in-cylinder temperature after compression should reach above 400℃, and the lowest temperature should not be lower than 350℃.

2. The viscosity of lubricating oil greatly increases or even solidifies at low temperature, which increases the engine starting resistance and fails to reach the minimum speed required for engine starting (generally above 100r/min (rpm)).

3. At low temperature, the terminal voltage of the battery decreases, the capacity decreases, and the charging is insufficient, so that the starting motor cannot reach the starting speed when driving the crankshaft, or even cannot move at all.

Solution:

1. If there is no fire in winter morning, first check whether the battery is charged and the electrolyte is sufficient. If the battery is fully charged, listen to whether the sound of the starter is strong enough. If the starter cannot be started, it needs to be maintained when the battery is fully charged, and the carbon brush and copper sleeve of the starter need to be replaced. If it is an operating vehicle, it is generally better to maintain the secondary starter before winter.

2. If the starter is powerful when it is over-started, but it can't catch fire, it means that the oil circuit is out of oil or the oil is below 0 degrees, and the oil tank should be baked. Oil tanks can be roasted with fire, but the fire should not be too big. Never bake the tubing to avoid fire. Baking the fuel tank is mainly to heat the fuel, and the best place to bake is the oil pump.

3. Use a blower to heat the diesel filter element and pipeline. In addition, in very cold conditions, it is best to heat the bottom of the oil, because the oil is in the oil pan after parking all night. The oil is sad in the morning. Even if it is started, it will cause great wear and tear to all parts of the engine and reduce the life of the engine.

Extended data:

Historical origin of diesel vehicles: 1892 German engineer Rudolf Diesel, based on the Carnot cycle in thermodynamics, imagined that the air sucked into the cylinder would be highly compressed to make its temperature exceed the self-ignition temperature of fuel, and then the fuel would be blown into the cylinder with high-pressure air to do work, which is different from the way that gas or gasoline engines suck in the mixture and ignite it to do work.

According to this principle, Dissel invented a compression ignition internal combustion engine fueled by diesel, which is the first diesel engine in the world and named after itself.

The high-power and high-efficiency diesel engine naturally became the ideal power source for vehicles, but at that time, the diesel engine was just starting and the technology was far from mature. It was undoubtedly quite difficult to put the diesel engine with huge volume and weight on railway vehicles.

1896, Herbert Stadt, a British engineer, designed and manufactured a railway locomotive using a hot-ball internal combustion engine and diesel fuel for the Royal Military Factory in woolwich, England. However, due to the design and technical defects, its engine power-efficiency ratio is very low, so it is called "quasi-internal combustion engine".

On the other hand, the appearance of this locomotive is undoubtedly an important step towards diesel locomotives.
