491Q?

Q's engines are divided into three types: (1) The old Toyota 4Y is imported from Japan, all of which are carburizers.(2) Single-point, use one ignition coil for every two cylinders. ( 3) More, now it's mostly this kind of engine. 491Q engine: The engine is a single-point electric injection engine with a 3-cylinder displacement of 660cc.

Q engine: The engine is a single-point electric injection engine with a 3-cylinder displacement of 660cc. QE stands for multi-point electric injection, and Q stands for single-point electric injection.

There are 13 kinds of engines of Golden Cup Automobile, which are 491Q-E; 494Q-ME; 4G24; 4G64; 4G22D4; 4G20; 4G20D4; V19; 4G19; 2RZ; 3RZ; B2C ; 495.

What is the reason for the slow fire position of the Golden Travel Sea Lion 491q engine?

The main reason is that the outside temperature is very low in winter, the gasification rate of our gasoline drops sharply, and the air mixer becomes very thin, which is not easy to cause combustion.

The reasons for the slow start of the car are as follows: slow start in winter: the temperature is low in winter. When the cold car starts, the temperature of the engine cylinder block is low, and the fuel is veryIt is difficult to atomize, resulting in the oil injected into the cylinder cannot be fully mixed with the air, and the gasification rate of gasoline drops sharply.

There are two reasons for the slow ignition of the car. 1. The battery is out of power, and the motor speed is low, resulting in a slow start of the engine. 2. It is the low compression ratio of the engine aging cylinder, resulting in slow engine start-up. The solution is to maintain sufficient battery power and overhaul the engine to solve this problem.

The rear oxygen sensor plug of the Fengjun 5491Q engine is broken, how to connect it correctly

1. If the rear oxygen sensor is broken, it will cause the car's power to decline and slow acceleration. Air-combustion is not accurate. Fuel consumption increases, because the carbon accumulation on the oxygen sensor will cause abnormal signal output, resulting in unbalanced engine mixing ratio and increased fuel consumption.With the increase of pollutant emissions, the annual inspection of exhaust emissions is not qualified, resulting in the annual inspection.

2. Unplug the wire harness plug of the oxygen sensor and use the multimeter resistance gear to measure the resistance between the heater connecting column and the iron connecting column at the end of the oxygen sensor. If it does not meet the standard, it means that there is a problem with the oxygen sensor. The oxygen sensor should be replaced in time to avoid abnormal guidance due to the oxygen sensor when driving. It causes a vehicle failure, which affects normal driving.

3. Preheat the engine to normal working temperature (or rotate at a speed of 2500 rpm for 2 minutes after starting). Check the connection problem of the negative probe in the voltage range of the multimeter in the E1 or battery negative socket, check the connection problem of the positive probe in the OX1 or OX2 socket, or connect the wire on the oxygen sensor harness plug.

4. If it is suspected that failures such as unstable idle speed or poor acceleration are caused by the oxygen sensor, you only need to unplug the oxygen sensor connector during maintenance. If the engine failure disappears, it means that the oxygen sensor has been damaged and must be replaced. If the engine failure persists, the reason should be found elsewhere.

5. Therefore, the oxygen sensor should be replaced or repaired as soon as possible after it is broken. Attachment: Detection method of oxygen sensor: Heater resistance detection: Unplug the harness plug of the oxygen sensor and measure the resistance between the heater wiring column and the grounding terminal in the oxygen sensor terminal with the multimeter resistance gear.

6. Yes, be sure to deal with it well. It will be more troublesome to replace it again.
