Chery injector

Types of Chery Injectors

As one of the most important components of a Chery vehicle's engine, the Chery injector atomizes fuel and delivers it into the combustion chamber. This process promotes optimal combustion, resulting in better performance, improved fuel efficiency, and reduced emissions. As technology advances, Chery injectors have also evolved to meet the demands of modern engines while adhering to strict environmental standards. Here are some common types of Chery injectors:

• Gasoline Direct Injection (GDI) Injectors

  GDI technology has become popular in modern Chery vehicles with gasoline engines. By injecting fuel directly into the combustion chamber at high pressure, GDI injectors enable precise control of the air-fuel mixture. This not only maximizes power output but also enhances fuel efficiency and reduces emissions. Additionally, GDI technology allows for multiple injection strategies, catering to different engine operating conditions and performance requirements.

• Multi-Point Fuel Injection (MPFI) Injectors

  Although older than GDI technology, MPFI injectors are still widely used in Chery vehicles with gasoline engines. In this system, each cylinder receives fuel from a separate injector, ensuring uniform distribution of the air-fuel mixture. While MPFI injectors may not offer the same level of precision as GDI injectors, they strike a balance between performance, emissions control, and cost-effectiveness.

• Common Rail Diesel Injectors

  For Chery vehicles equipped with diesel engines, common rail diesel injectors play a crucial role in optimizing fuel delivery. These injectors are connected to a shared high-pressure fuel rail, allowing for precise control of injection timing and quantity. Common rail diesel injectors enable multiple injection events during each combustion cycle, contributing to smoother engine operation, lower noise levels, and improved emission performance. This technology has made diesel engines cleaner and more efficient.

• Turbo Gasoline Direct Injection (TGDI) Injectors

  Chery's high-performance vehicles utilize Turbo Gasoline Direct Injection (TGDI) technology. TGDI injectors cater to the demands of turbocharged engines, delivering precise and rapid fuel delivery at high pressures. This ensures optimal combustion even under high boost pressure, resulting in increased power output, torque, and overall engine efficiency. With TGDI technology, Chery's turbocharged gasoline engines deliver thrilling performance while meeting stringent emission standards.

Specifications and Maintenance of Chery Injectors

Below are the specifications of Chery injectors.

• Flow Rate

  Chery injector flow rate is measured in milliliters per minute. This is the amount of fuel an injector can dispense into the engine's combustion chamber. For instance, a Chery Tiggo injector may have a flow rate of 400 ml/min. This means each injector sprays 400 milliliters of fuel every minute into the engine.

• Spray Pattern

  Chery injector spray pattern indicates how the fuel is sprayed into the engine. The pattern can be conical or hollow. A conical shape resembles a triangle pointing down. It sprays fuel in a wide area like a shower. A hollow spray pattern has a hole in the middle. This type sprays fuel on the engine's walls. For example, a Chery injector might have a conical spray pattern. This helps mix fuel and air better in the combustion chamber.

• Operating Pressure

  Chery injector operating pressure is the force with which fuel is pumped through the injector. This pressure is typically around 3 to 4 bars (about 43 to 58 psi). To visualize this, think of a bike tire. A bike tire is inflated with a pump that has 3 to 4 bars of pressure. Just like the tire needs that pressure to function properly, the fuel injectors need the same pressure to spray fuel accurately into the engine.

• Electrical Resistance

  Chery injector electrical resistance is like the difficulty electric current experiences while moving through the injector. It is measured in ohms, with values ranging from 12 to 16 ohms. This can also be compared to a water pipe. The electrical resistance is similar to a water pipe with restrictions. The water (electric current) has trouble flowing through it. Just like the pipe with restrictions impedes water flow, the electrical resistance in the injector makes it harder for the current to flow.

• Construction Material

  Chery fuel injectors are made of stainless steel, plastic, and aluminum. Stainless steel is similar to the strong metal bars found in concrete buildings. It can endure high pressure without breaking. Plastic is as light as the materials used to make water bottles. Like those bottles, plastic in the injector can handle heat without melting. Aluminum is comparable to the light materials in cars, such as in the engine. It is lighter than steel but still robust. These materials work together to create a durable injector that can withstand the pressure and heat of the engine.

Chery diesel injector maintenance is essential to ensure they function properly. Here are easy steps to follow:

• 1. Regularly Clean the Fuel System: Cleaning the fuel system is like washing clothes. Dirt and grime build up over time. Use a fuel system cleaner every 10,000 kilometers or as needed. This helps remove any clogged dirt or deposits from the injectors. Clogged injectors can make the car run poorly, just like stains make clothes look bad.
• 2. Use Quality Fuel: Using good fuel is essential for the car, just as healthy food is necessary for the body. Fuel with the recommended octane level helps the engine run smoothly. The octane level is like the energy level in the food. Avoid using low-quality fuel or additives, as this can damage the injectors. Just as junk food can harm the body over time, low-quality fuel can harm the injectors in the long run.
• 3. Replace the Fuel Filter on Time: The fuel filter is vital for stopping dirt and impurities before they reach the injectors. It is like a sieve that catches unwanted stuff. Changing the filter every 30,000 kilometers or sooner is important. This ensures the injectors stay clean and work well, just like a clean sieve ensures only clean water flows through.
• 4. Check and Adjust Fuel Pressure: Fuel pressure is the force with which fuel is pumped to the injectors. It needs to be just right, not too hard or too soft. A pressure gauge measures the pressure. If the pressure is low, a fuel pressure regulator adjusts it. This ensures the injectors spray fuel correctly into the engine, like a garden sprayer misting plants evenly.
• 5. Inspect Electrical Connections: Inspecting the electrical connections to the injectors is vital. It is like checking the wires for a light bulb to make sure it works. Problems like loose plugs or damaged wires can stop the injectors from getting power. Just as a loose wire can make the bulb flicker, loose or broken electrical connections can make the injectors spray fuel unevenly.
• 6. Perform Engine Tune-ups: Engine tune-ups are like regular check-ups for car health. A mechanic tunes up the engine and checks if all parts work well together, just as a doctor examines the body to ensure all systems function properly. This helps keep the engine running at its best, like a healthy body.

How to Choose Chery Injectors

When looking for the right Chery injectors for any business, consider the following factors.

• Vehicle Model

  Considering the vehicle model is important because different vehicle models may have engines that require fuel injectors with different specifications or performance characteristics. For example, a high-performance sports car may require fuel injectors that can deliver fuel more precisely and in greater quantities than a fuel injector that is simply reliable and efficient. As a result, one vehicle model may specify fuel injectors with certain flow rates and spray patterns, while another vehicle model may use fuel injectors with different specifications. Therefore, it is important to ensure that the fuel injectors match the requirements of the specific vehicle model to ensure optimal engine performance, fuel efficiency, and emissions control.

• Engine Type

  Considerations about the engine type are important because engines can have different configurations and characteristics that affect how fuel is delivered and burned. For example, a turbocharged engine may require fuel injectors that can deliver more fuel at higher pressures to support the increased airflow from the turbocharger. In contrast, a naturally aspirated engine may not need as much fuel or as much injector pressure. Additionally, diesel engines and chery car engines may have different requirements for injector design and operation due to differences in fuel properties and combustion processes. Therefore, it is important to choose fuel injectors that are compatible with the specific engine type to ensure proper fuel atomization, distribution, and combustion, leading to better engine performance, efficiency, and emissions control.

• Engine Specifications

  Engine specifications such as cylinder capacity, power output, and torque are important considerations when selecting fuel injectors. This is because these specifications give an idea of the engine's performance characteristics and fuel requirements. Higher-power and higher-torque engines tend to generate more power and require more fuel to be delivered to the combustion chambers to support their performance. As a result, such engines may need fuel injectors with a higher flow rate to deliver the additional fuel required. On the other hand, engines with lower power output and torque may need fuel injectors with lower flow rates to match their fuel needs appropriately. Choosing the right fuel injector based on engine specifications is essential for optimal engine performance, fuel efficiency, and emissions control. Incorrect injector selection can lead to issues such as lean or rich fuel mixtures, affecting engine performance metrics and potentially causing long-term damage to the engine.
