Mercedes Benz Engine


This project was delivered to a US oil company, instrumenting Mercedes Benz engine for component performacne evaluation.


Tappet rotation is one of the key tribological parameters that play an important role in component wear. Lack of available techniques has discouraged researchers from performing such studies on real production engines. In this project, a novel experimental technique has been developed that allows the measurement of tappet rotation speed on any engine having direct acting tappets. This unique method does not require any changes or modifications to the components or engine itself. Using this innovative technique, for the first time, all the tappets of a single camshaft have been instrumented and tappet speed was measured at different operating conditions verifying that not all the tappets behave in the same way. Experimental results clearly showed that all tappets do not respond to the change in lubricant viscosity and the direction of tappet rotation may be one of the factors influencing the performance.

Audi Engine



This was a consultancy project for a European Oil giant. The project was to instrument the Audi engine with state of the art sensors to understand the effect of egnine operating conditions on component performance. The engine was instrumented in such a way ensuring the components operate under original environment with no modification to the components under investigation. This is a confidential project and thus the details cannot be revealed.

Toyota Valve-train


This work was carried out for a European oil giant, looking at the effect of lubricant formulation on engine performance.


Real production engine employing end pivoted roller follower valve train has been instrumented to investigate the effects of engine operating conditions, lubricant rheology and chemistry on the sliding of valve train roller followers. The test results showed that due to shear drag it was not necessary for roller rotational speed to increase with camshaft speed. The lubricant viscosity played a key role in the roller slip at lower temperatures however at higher oil temperatures negative slip was also observed indicating that component inertia and internal friction have a role to play in roller slip. The results also clearly showed the impact of viscosity improvers on roller slip. The design and development of experimental set up, instrumentation and test procedure was the objective of this work.

Cummins HDD


In this project new systems have been developed that allow measurements of a number of parameters vital for evaluating the cam/tappet interface. One of the main reasons for developing these techniques was to allow the study of the cam/tappet interaction in its original environment. The experimental system developed allows the measurement of cam/tappet friction on a gear-driven pushrod valve train configuration. With the help of a recently developed new technique for measuring tappet rotation, the tappet speed can also be measured along with the oil film thickness at the cam/tappet interface using the capacitance technique. All the three main parameters – friction, oil film thickness, and tappet rotation – have been measured for a range of engine conditions and lubricant types. The experimental techniques used were developed in such a way that the modifications had no detrimental effect on the cam/tappet performance.

The independently driven oil delivery system has a dual control mechanism, constant speed and constant pressure. Plate type heat exchanger with the oil heating and cooling system gives the flexibility to run the rig at near subzero to 125 degree centigrade. Tappet rotation, roller slip ratio, oil film thickness at cam/tappet/roller interface, camshaft average as well as instantaneous friction torque are some of the parameters that can be measured using this test rig.

Engine Blowby measurement system



One of the most challenging parameters to measure accurately in engine testing is engine blow-by. The blow-by flow rate of engines is very low and thus is difficult to measure through conventional means. Special techniques are used to measure such limited flow rates.

Leak Detection System for Radiators



Leak Detection System for Radiators was especially designed and developed for Radiator Manufacturers. This system is adopted to replace the conventional wet testing where the radiator is pressurized and dipped in water tank for visual detection of leak. The drawback of such method is the water scale marks left on the product after the completion of the leak test. One of the main advantage of using our system for leak detection is that the product is shipped in mint condition with no scale marks on the product.


Based on the sensitivity selected by the user, one of the three techniques of measuring leak is adopted for greater accuracy. The leak is detected through pressure decay, pressure differential and air mass flow rate.  


The system can be connected to a PC via usb port. User friendly software gives the user complete control. Leak size and sensitivity can be adjusted with a click of a button. The system logs the data and continuously monitors the total number of pass-fail units.
