Buick Junyue 3.0lf1 first cylinder lack of fire

Ignition system failure: including spark plugs, spark plug coils and ignition control modules, etc. You can check whether these components are damaged or need to be replaced. Fuel system problems: including faults such as fuel pump, fuel injector, fuel filter and fuel pressure regulator. You can check whether these components are working properly or need to be replaced.

As a medium-sized car, Buick Regal is equipped with a 0t in-line four-cylinder turbineIn the supercharged engine, the vehicle has a lack of fire in the one-cylinder air conditioner. It is recommended to consider checking whether there is a problem with the ignition coil or the spark plug is not good at ignition. During the warranty period, you can consider free 4s store for maintenance.

Common faults of low-voltage circuits: insufficient battery storage; poor wire connection or disorder; poor battery ironing; damage to the distributor or Hall sensor; damage to the ignition switch or poor wiring; damage to the transistor ignition control unit or poor wiring.

Replace the ternary catalyst. The solution to the Buick engine fault indicator light is as follows: the exhaust emissions do not meet the standard. For example, poor fuel, ternary catalyst failure, excessive carbon accumulation in the intake pipe, blockage of fuel injector, oxygen sensor failure, occasional engine lack of fire, etc. will all cause the engine fault indicator light to light up.

LF1 engine disadvantages

The power of the engine is obviously insufficient, especially when you relax the accelerator pedal to slow down or put the gear selection handle in the N position when driving at high speed, you can feel that the speed is obviously decreasing too fast, and the ride comfort is worse.

Year Cadillac CTS v6 0. LF1 engine, in-cylinder direct injection machine, shutdown delay, and mixed gas concentration, it is recommended to check whether the fuel injector of the car needs to be cleaned. Generally, the fuel injector of the engine is too dirty, which may lead to.

When the valve is opened, the pressure difference and the high pressure of the gas itself increase the air intake and improve the power; the naturally aspirated engine has a direct impact on the stability and responsiveness of the power output, which is far superior to the supercharged engine. The current V84LF1 engine is the best example.

At present, the LF1 engine is mainly installed on Buick New Junyue, Cadillac CTS/SRX and other models, while its multi-fuel version of the LFW engine is only equipped with GMC Terrain and Chevrolet Equinox models, and the maximum power is increased from 203kW to 2 05kW, the torque was increased from 353Nm to 400Nm, an increase of 47Nm.

What is a self-aspirated engine?

The self-aspirated engine does not have a supercharger, that is to say, the air body only enters the "cylinder" through the air filter - throttle valve (usually called "throttle valve") - intake manifold, and gasoline is directly injected into the intake manifold through the fuel injector.

Natural intake is a form of car intake. It does not require any supercharger to press the air pressure into the combustion chamber.Natural intake without supercharger means that the air reaches the cylinder through the throttle valve (commonly known as the throttle valve) intake pipe of the air filter, and the gasoline is directly injected through the injector in the intake pipe.

Naturally aspirated means that in the first stroke above, the mixed gas is sucked by the naturally formed pressure difference. The supercharged type is to compress the gas with the fingertips to improve the pressure and density of the gas. When the valve is opened, it relies on the pressure difference and the high pressure of the gas itself to increase the air intake and improve the power.

Buick Junyue 3.0v6 engine model

It seems that 0 has a discount of 100,000, that is, 290 direct injection should It's Junyue's top-equipped model. The quality is not so good, but it's too expensive. The maintenance cost is very high, which is equivalent to 2 4 direct injection engines together. I'm sure, 0 up to 15-16L oil, and the air conditioner is turned on in summer, and the key is No. 92 oil.

LV6SIDI. According to the detailed introduction of Junyue on the official website of SAIC General Motors, Junyue introduced the direct injection V6 engine and 0LV6SIDI engine in the middle and high-end car market for the first time.

The Buick Junyue is the largestThe power is 192kW, and the maximum torque is 350Nm, bringing a powerful power output in the full-speed segment. With ETRS electronic gearshift and steering wheel shift paddle, it makes the driving experience higher.

LF1 engine parameters

1. This engine adopts a cast aluminum cylinder block and double overhead camshaft design, with a maximum power of 191kW and a maximum torque of 350N·m. In addition to the LF1 engine, Buick Junyue is also equipped with other models of engines, such as 0T, 5L, etc.

2. The Cadillac CTS 0 version adopts this LF1 engine, with a maximum torque of up to 300Nm, which is only slightly lower than the old 6L engine, but the power is 3kw higher.

3. When there is a traffic jam or idle for a long time, the engine water temperature gauge is too high, the high-speed transmission of the electronic fan is too long, the engine noise increases, and the fault is the most obvious when the air conditioner is turned on when the temperature is too high. Check whether there is too much dust between the condenser and the water tank, and clean it thoroughly with high-pressure air to ensure that the water tank and the cold The condenser has good heat dissipation performance.

4. When the valve is opened, the pressure difference and the high pressure of the gas itself increase the air intake and improve the power; the naturally aspirated engine has a direct impact on the stability and responsiveness of the power output, which is far better than the supercharged engine. The current V84LF1 engine is the best example.

5. About 14 oil in urban areas, and about 10 oil on high speed.

6. Year Lexus rx300 is equipped with a 20T inline four-cylinder turbocharged engine in terms of power. The Lexus RX300 is equipped with a 20T inline four-cylinder turbocharged engine in terms of power, with a maximum output power of 170kw.
