“…A computational study was performed for the air-intake system of a CRDI (common rail direct injection) engine at 1,600 rpm. The model delivered a minimum pressure drop of 5 mbar at the air filter and delivered a higher-pressure drop at pipe joints (Joshi et al, 2007). Idris and Bakar (2009) studied the effect of the port-injector with a sequential injector.…”

The bioCNG with 90% of methane makes a potential renewable alternative of CNG for the application in dual-fuel diesel engine. The bioCNG is to be inducted in the manifold through port injection. The work is aimed to find the optimum port length and port-injector diameter. The objective is to mix bioCNG homogenously with air, before entering the engine. This would create an opportunity for major replacement of diesel to reduce the running cost of the vehicle. The two injector diameters (7 mm and 10 mm) and four port lengths (0 mm, 100 mm, 150 mm and 200 mm) are investigated. The manifold has a diameter of 28.5 mm and the port-injector is inclined at 35° to the manifold axis. The geometries are simulated in ANSYS Workbench 19.2, and post-processed in Tecplot. The results show that the port length of 200 mm with an injector diameter of 7 mm delivered homogeneous mixture in dual-fuel mode.

This paper was to analyze the air intake system of turbo charged diesel engine. This was done by measuring the pressure drop across the air filter in the air intake system. Both static and dynamic measurements were conducted with the help of pressure measuring devices such as U -tube manometer and vacuum gauge. The point of measurement was at the tapping provided for restriction placed in between air filter and turbocharger compressor. Vehicles from various categories such as passenger vehicles, light commercial vehicles (LCV) and heavy commercial vehicles (HCV) were taken up and analyzed.
