There are several different ways of visually accessing the combustion chamber in an internal combustion engine. Optical access is provided through a 20-30mm length fused silica liner and a sapphire window in the piston crown. An extended piston allows a 45° mirror to be located between the upper and lower piston crowns allowing illumination or viewing into the cylinder from below. A maximum engine speed of 1000 rpm can be achieved through the use of light weight materials for the piston components and the use of primary and secondary balance shafts in the crankcase. The piston is manufactured from aluminum while the piston crown is made from titanium, chosen due to the similarity in thermal expansivity between titaniumand sapphire.

The LPG injection kit is suitable for any single cylinder engine. The LPG is injected in the manifold of the engine intake. The Electronic Control unit of a standard after market LPG Kit cannot be adopted for use in research engine, because of the fact that in a standard LPG kit the injection start angle and the duration of injection are results of preprogrammed value from multidimensional maps in the ECU.While a part of the research requirement it self is finding the optimal Map values at conditions/variable as desired by the researcher.Hence we provide an open loop Electronic Control Unit (OPECU) where the user can decide the injection start angle and the injection duration. This Electronic Control Unit is designed, programmed and tested in our company and are not available in general market/not for open market. Our Electronic Control Unit is only sold to high end research users.

The EGR system is designed to reduce the amount of oxides of nitrogen(Nox) created by the engine during operating periods that usually results in high combustion temperatures, NOx is formed in high concentrations whenever combustion temperature exceed about 2500˚F. The EGR system reduces NOx production by recirculation small amount of exhaust gases into the intake manifold where it mixes with the incoming air. By diluting the air mixture under these conditions, peak combustion temperature and pressure are reduced, resulting in an overall reduction of NOx output. Provision is been made to change the percentage of EGR.

This system is designed to study the thermal radiation of a given two identical specimen (made out of homogeneous material) one with black coating and other without coating. This system helps students to study the emmisivity of non-black surface during the charge. The setup consists of two circular brass plates identical in size and is provided with heating coils at the bottom. One of the brass plates is coated black in colour, which is called black body and the other gray body. The plates are mounted on asbestos cement sheet and surrounded by a wooden enclosure so as to provide undisturbed natural convection surroundings. The heat input to the heater is varied by Variac and is measured by Ammeter & Voltmeter. A temperature indicator with a selector switch is provided to measure the various temperatures of the specimen

This apparatus enables the student to study the characteristics of composite structures and its heat transfer ability across the composite walls by altering the combination of slabs. The apparatus consists of three slabs of different materials of same thickness. The slabs are brought together in contact. The three slabs are brass, M.S and asbestos. One surface of the slab is electrically heated and the other end is cooled, .the temperatures of the slabs are measured using thermocouples and are indicated by temperature indicator. The power Input to the heater is measured by Voltmeter and Ammeter.
