Diagnostics of many different systems can be complex and time-consuming. The longer it takes to diagnose one car, the fewer cars will be inspected during the working day. Pyrometers speed up the diagnostic process. Point the pyrometer at the object, pull the trigger and read the temperature value.
Finding engine malfunctions
The reason for poor engine performance are the following factors: low compression, problems with the ignition system, clogged fuel injectors, incorrect fuel-air mixture, etc. Connecting diagnostic devices and analyzers - for example, an oscilloscope - to a running engine takes a long time. With the help of a portable non-contact thermometer, engine diagnostics is much faster and easier.
Problems with the ignition system
With the engine running, measure the temperature of the exhaust manifold of each cylinder and compare the temperatures. A low cylinder temperature indicates a spark plug breakdown. It is also possible to diagnose a diesel engine for lack of compression or to determine a non-working cylinder by measuring the temperature of the engine block or exhaust manifold.
Adjustment of the fuel-air mixture
Measure the temperature of the exhaust manifold, exhaust pipe or distribution pipe. Exhaust temperatures will be higher if the mixture is depleted, or lower if the fuel injector is clogged. This measurement technology is necessary to establish an optimal fuel mixture and balance between the cylinders.
Diagnostics of the cooling system
If the engine overheats and no coolant leaks are detected, the cause may be a blockage of the radiator, a failure of the thermostat or cooling fan, a worn-out water pump impeller. Using an IR thermometer, you can quickly and easily identify the source of the problem and troubleshoot.
Check the temperature of the cooler in the radiator inlet pipe. If the fan is running, scan the entire surface of the radiator and find the low temperature points that indicate a blockage of the pipe in this place. The temperature should gradually decrease from the inside of the radiator to the outside and from the top side to the bottom.
Turn on the engine before it warms up. Measure the temperature of the upper radiator hose and the thermostat housing. When the engine temperature reaches 82 ... 104°C, the temperature of the upper radiator hose should rise again when the thermostat is open. The absence of temperature change means that there is no coolant supply and the thermostat is clogged.
Coolant temperature sensors
The warm-up time and operating temperature play an important role for cars equipped with a direct injection system. Measure the cooler temperature sensor and the air duct system temperature sensor and compare these two values with the computer readings. If they work correctly, the temperature difference should be only a few degrees.
Climate control
Fans, stoves and air conditioners are used in the car.The correctness of their operation can be checked using non-contact thermometers.
When the engine reaches the correct operating temperature, check the cooler temperature at the upper radiator hose. (should be about 93°C). If it is lower, the thermostat is clogged.
Then check the temperature of the inlet and outlet hoses of the stove. They must be hot, and the temperature of the intake hose is not higher than 7 ° C. If the exhaust hose is not hot, the cooler does not pass through the stove, the passage of the stove is clogged or the furnace control valve (if used) is not open.
Air conditioners
Turn on the air conditioning system for a few minutes, then measure the temperature of the ventilation exhaust passage inside the machine. Measure the temperature of the hood at an angle, and not at the air passage itself. Compare the readings with the factory specification. You can also measure the temperature of the evaporation system of the condenser and compare these readings with the manufacturer's specification. Low pressure or refrigerant charge can be determined by measuring the temperature of the condenser and duct, then compared with the factory specification.
Tires and braking system
To diagnose the effectiveness of the braking system, measure the temperature of the rotor or brake drum immediately after the car accelerated in a straight line and braked sharply. If the rotor and drum temperatures are very different on the brake wheels, it is possible that the brake pads slip, which causes uneven braking. The malfunction of wheel bearings and brake pads is determined as follows: measure the temperature of the bearings – the temperature significantly higher than the ambient or different on different bearings indicates its wear.
