Car “Gazel-405" of the engine the injector of which was obtained by the injection system, which allows efficient use and distribute the fuel mixture the system used in cargo transport. The design of the power unit differs from its predecessor by the presence of 16 valves. This engine belongs to series ZMZ produced by Zavolzhsky plant.

Gazelle 405 engine injector

How it works fuel injection motor?

The Principle of operation of a fuel-injected engine is the fuel delivery via the injectors, and adjustable electronic control unit (ECU). The controller monitors the status parameters of the power plant, need to calculate the flow and the quantity of the fuel provides the adjustment of the fuel flowing through the pulse duration.

The ECU is able to evaluate the results of calculations and commands, and to remember previously executed manipulation, coordinating further action with him. Intelligent process development unit happening constantly and lasts for the whole lifetime of the car. The flow of fuel in the car «Gazel-405" (engine injector) can be done in two ways:

  1. Synchronous variant with fixed position of the crankshaft.
  2. Asynchronous flow - regardless of the crankshaft.

The First method is advantageous. Asynchronously fuel normally is supplied at startup of the power unit. The injectors are activated in pairs or one at a time.

Features

Injection engine for cars ‘Gazelle-business” has the following specifications:

  • Motor Type – four-stroke petrol engine with 4 cylinders.
  • Injection System ­– microprocessor control with ignition and air supply.
  • Displacement (CC) – 2 464.
  • Standard power at a speed of 4.5 thousand revs – 214 Nm.
  • Filter – air dry replaceable element.
  • Cooling system   of closed type with forced circulation.
  • Generator – with integrated unit and the voltage controller.
  • Sensors system overheating and oil pressure.
  • Starter – remote, solenoid option with the reducer.

Technically, the engine volume 2,46 liters capacity of 140 horsepower allows the car to overtake, to perform a steep maneuver with a full load.

Capabilities of the power unit

Car Owners “Gazel-405" engine-injector is impressive especially with increased fuel consumption. He is 8 liters on the highway to 13 in the combined cycle when driving in the city. Also used oil: about 100 grams per thousand kilometers. In single-point manifold system equipped with only one injector for all cylinders. In the distribution block, each of them has its own header. And with direct injection the fuel is fed directly to the cylinders like a diesel motor.

Injection cars are more economical due to exact dosing. In addition, the environmental friendliness of the exhaust gas entering into the environment, corresponds to the standard "Euro 3", power rating increased by 10%.

The power unit is adapted to local climatic conditions. It tolerates heat, cold and sudden temperature fluctuations. The power plant is accurately and functions reliably in the most harsh and difficult climates. She starts in the bitter cold.

Faults and Troubleshooting

As with any technical product, the motor "Gazelle-Business” is prone to breakdowns. Sometimes it needs maintenance for various reasons. Most often have such problems:

  1. The Motor does not start. Likely to the injectors no fuel. You must use the appropriate fuel, wash and clean the pickup screen.
  2. The sealing of the pipeline between the tank and the pump. You should check the joints and restore integrity.
  3. You have a problem with the control electronics. Need to replace a faulty node details.
  4. Weak power set indicates problems in electronic control system.After testing, you need to replace the bad element.
  5. Occurs clogging of the fine filter. This requires replacement of the filter element.
  6. Air in the fuel block. You need to check and ensure tightness of the system.
  7. In case of any malfunctions in the fuel pump, replace the faulty injector.

Repair and adjustment

Incorrectly adjusted fuel pumps ‘Gazelle-405" (injector) provoke an increase in fuel consumption and the emergence of unnatural black smoke. For Troubleshooting, you must adjust the operation of the pump and the injection angle. Non-working atomizer requires timely replacement. And grey smoke from the exhaust system indicates excessive oil consumption. This may be due to worn piston rings that need to be replaced.

In case of wear of the guide sleeves or bearings of the crankshaft need to be replaced with new elements. Too white smoke from the exhaust system said to increase fuel consumption. In this case you need to replace the injectors. If not start by “Gazel-405" (the injector), check thermostat (replace if needed) or clean the intake of fuel, to ensure the normal supply of fuel to the injectors.

Gazelle will not start the injector 405

Services and prevention

The Principle of operation of fuel injection of the engine based on the fuel control electronically. Thanks to this preventive maintenance to the motor required approximately every 12 thousand kilometers (manufacturer's recommendation). This made changing the oil and filter.

If ‘Gazelle-405" (engine-injector) works in an intensive mode, it is recommended to service the motor every 8-10 thousand kilometers, since at high loads the oil faster changes the chemical composition and loses its properties.

Adjustment of the valve setting appropriate goals: recommended after every 15 thousand. In addition, it is necessary to check the gas distribution mechanism, since a broken belt can lead to deformation of the valve, resulting in expensive repairs or even replacement cylinder head.
