Leak Testers in Automotive Fuel and Brakes

The crucial entity for the safety measures of any vehicle is its brakes and calipers that falls under the category of most important components of the braking system. The force applied to slow down and stop the vehicle comes from the brakes. Calipers must be of the quality which stands the test of time, wear and tear. Dis-functioning of the caliper will keep the car moving even when one doesn’t wish to. The automotive industry follows the three types of dry-air Leak testing that are the pressure decay, differential pressure decay and the third is mass-flow leak testing decay.

The injection system of the vehicle transfers the fuel into the cylinders of the engine, whereas to produce the power to the engine gas is burned. A leaky fuel injector can impact the performance of the vehicle and lead one problem to another. Even the small things like erratic engine idle, an engine that is misfiring, reduced gas mileage all this can lead to the engine blocking and worst case worst it can ignite the engine causing an engine fire.
Fuel injection demands fully-fledged air leak testing to enhance the functioning of vehicles. One must test separately with various limits for the same test cycles for body welds, seat leakage and overall leakages too. Merging of the instrument software, fixture, and circuit test is necessary so is full test documentation.

Test process of downstream performs a micro-flow mass-flow transducer that offers 15 times great leak sensitivity than any of the dry test method. A test part is circuited with the test chamber and the leakage is measured by calculating the flow present outside the part, excluding the requirement of the pressure stabilization inside the part. The test circuit is intentionally designed for lesser volumes allowing the quick detection of the leak by the testers.
It is extremely crucial for small and quick testing, everything from fixtures and clamping design are crafted and built for exact precision and prevent any movement during the testing. The mechanism of the seal positioning constantly points the test part firmly, stabilizing the forces of the closure real quick to reduce the cycle times.
Seals are made to produce high durability to help the different parts run thousands of times without any replacement.

Let us see some special features
Air Leak testing is extremely important to perform the fail-safe operation. It makes use of low-level air flow to define the quality of test-circuit integrity prior to every test cycle.
Temperature compensation edges the accuracy of the test by depleting the residual heat from welding, fabrication, washing and even operator handling. Custom algorithms emerged from the special cooling features of testing provides the exact response throughout the test cycle.
The dry air test works for both water and oil at the same time, that too fast.
There are also some helium leak detection methods that are as follow:
 Sniffer
This works by pressurizing the item with helium where a connected sniffer finds the leak. This method is slow and non-quantitative but with the ability to locate the leak.
 Accumulation
Here the item is placed in the helium chamber. The effect is inexpensive but comes with many disadvantages.
 Vacuum leak testing with helium
In this method, the spectrometer works as a medium to detect the leak.
