Imperial Auto caters to the major sub assemblies such as EGR, SCR & Urea Line under after treatment and exhaust assemblies. EGR Line: EGR tube assembly carries unburnt gas vapours from the exhaust manifold chambers to the intake manifold and is reintroduced into the engine firing sequence. It is used in conjunction with catalytic converter for better performance. It also enhances the life of critical engine moving parts. The gases are cooled before they are fed back. SCR Line: Selective catalytic reduction is used in larger diesel engines usually found in commercial vehicles. Our SCR lines are fully tested with short de- freezing time, low permeability and abrasion resistant shielding Urea Line: Imperial Auto manufactures Urea lines with high quality and high temperature plastic given its critical role in SCR system.
