The Bosch SMT 300 Smoke Tester is an integrated device which enables the factory to do a multitude of auto leak detection testing on vehicles. Utilizing OEM approved technologies, EVAP spray testing is created quick, accurate and easy. It is able to be used in closed as well as open systems and is therefore very flexible to any type of manufacturing company.
An EVAP spray is used in this system to test the temperature of a fluid or coolant. The temperature of the "hot" fluid will be tested while the coolant will be subjected to pressure while being fed through a boost loss into the engine. Once the intake manifold pressure is equalized with the pressure of the booster pump, the coolant will then be fed at a higher pressure into the engine thus causing a "hot" or "smoke" sample. This will allow a technician to determine what the source of the leak is and therefore fix it before it creates engine damage.
There are many reasons why a boost leak may occur. Boost leaks can often occur when a connection is removed or a valve has been improperly installed. In addition, when the turbo system is unplugged, the pressure test will not run. Boost leaks can also occur when a solenoid is damaged or when the timing belt is malfunctioning. All of these events will cause the pressure test to fail at one time or another when using a Bosch smoke tester.
The Bosch Smoke Tester machine comes with a high-performance digital control valve and a digitally adjustable air control valve. The machine is fully programmable for any type of testing environment, including an open or closed system. The digital control valve allows the operator to program the machine to different measuring sequences for specific testing environments.
The machine also comes with a built in flue gas analyzer that provides the owner with the ability to measure and interpret performance of the combustion process and flue gas. The flue gas analyzer can measure the rate of soot production, the temperature of the combustion process, the combustion pressures, and even the volumetric percentages. The smoke tester can also be programmed to provide a maximum output of smoke number and maximum flow rate.

This article is not a substitute for the expertise of a licensed fuel burner inspection technician. Professional fuel burner inspections should always be performed by trained professionals in order to prevent damage or loss of engines or other working parts while fuel is burned.
A third alternative to the oil burner inspection and testing procedure is the use of the infrared camera mounted accessory. This accessory is ideal for oil burner inspections because it offers a highly advanced third-party inspection method that is in compliance with the Society of Automotive Engineers (SAFE) guidelines and the fourth generation of the True Spot Smoke Test Method. With the True Spot Smoke Test Method, the camera is able to measure and interpret volatile organic compound (VOC) emissions from an engine without changing the fuel or removing any filter elements. This third alternative to the oil burner inspection is highly recommended for any vehicle that could be potentially affected by a possible increase in emissions.
It is important to note that having a fuel or flue tank pass all the necessary tests does not necessarily mean that there are no leaks within these tanks. Fluid leaks often occur when certain products like anti-freeze or antifreeze are used in an engine. If you notice any signs of a possible leak such as excess condensation build up or visible condensation on the side of a fuel tank or on the underside of a fuel tank lid, it is important to contact a professional leak detection and repair service right away to prevent any potential catastrophic event from occurring. Once your fuel tank has passed all tests, you can continue to work on keeping your engine running smoothly and safely.
