Electric oil pump in the engine oil fault application
An Isuzu NHR van can not start its engine every morning, but use another car to drag, and it takes a long time for the engine to start. One day, the driver just driving on the road, step on the accelerator plate found: If the accelerator pedal is released, the engine can still smooth low-speed operation. As a result, the driver sent the car to our factory repair. Inspection showed that the fuel injection solenoid valve on the injection pump and return valve are good, so decided to test the fuel system with DC method, with a rubber tube to the fuel injection pump directly into the starter, and then repeatedly stepped on acceleration pedal. The engine runs normally during the test, which shows that the high-pressure pump head and injector of the injection pump have no trouble, and the second-stage vane pump has a fault. After the diesel fuel injection pump inlet pipe installed a QB111 electric pump (fixed on the truck's longitudinal beam, the power line connected to the injection pump power terminal), the troubleshooting. The truck has been traveling more than 10,000 KM normally. Later, in order to solve a Isuzu NKR truck fuel pump is not the problem of oil, the car was equipped with electric fuel pump; then successfully in a 2.5T forklift with electric pump to replace the damaged mechanical Oil pump, saving thousands of dollars in repair costs. Electric trikes, also known as electric tricycles or e-trikes, are three-wheeled vehicles powered by an electric motor. They provide an alternative mode of transportation for people who may have difficulty riding a traditional bicycle or motorcycle. E-trikes are becoming increasingly popular due to their ease of use, stability, and eco-friendly nature.

Test showed that the phenomenon of failure is true, so that the engine oil fault. As a result, the diesel filter was replaced and the low pressure tubing was blown with compressed air. The pump was then filled with diesel oil and air was removed using a hand pump on the water separator. The engine was then started and the accelerator pedal was depressed. At this point, the engine speed from low speed has been rising to high speed, but the engine speed at high speed for more than ten seconds to automatically reduce the speed, and that is, then repeatedly depress the accelerator pedal, the engine speed can not be increased .
Features of electric trikes may include:
1. Electric motor: E-trikes are equipped with an electric motor that provides power to the vehicle. The motor can be located in the front or rear wheel hub or centrally mounted on the frame.
2. Battery: Electric trikes are powered by rechargeable batteries, typically lithium-ion batteries. The battery capacity determines the range of the trike, with higher-capacity batteries offering longer distances per charge.
3. Pedal-assist or throttle control: E-trikes can be operated using pedal-assist mode, where the electric motor provides assistance while pedaling, or throttle control mode, where the motor is engaged by twisting a throttle grip or pressing a button.
4. Braking system: E-trikes are equipped with brakes to ensure safe stopping. Common braking systems include mechanical disc brakes or hydraulic disc brakes.
5. Cargo capacity: Some electric trikes are designed with cargo carrying capabilities, such as a rear cargo basket or a front-mounted cargo box. These trikes are often used for commercial purposes, such as delivery services or food vending.
6. Suspension system: To enhance comfort and stability, some electric trikes feature suspension systems. This helps absorb shocks from uneven terrain and provides a smoother ride.
7. Lights and indicators: Like other vehicles, electric trikes may have headlights, taillights, and turn indicators to improve visibility and safety on the road.
