Abstract: The present invention is related to a vehicle provided with operation selection mode. In particular, the present invention is related to a common rail electronically controlled vehicle provided with operation selection mode wherein the user can select either of the power mode and the economy mode of vehicle operation depending on the road conditions. The system of the present invention provides a system to enable selection of power mode operation for power conscious driving requirement or economy mode operation for fuel conscious driving option obviating the use of additional interface devices between engine and engine control unit.

Abstract: A housing for a thermostat includes a body, a cavity, at least one director member and at least one retainer member. The body defines an enclosure that receives coolant fluid. The enclosure is in fluid communication with a pump that pumps the coolant fluid to a sink for dissipating heat extracted by the coolant fluid. The cavity configured on body receives and holds thermostat that determines temperature of coolant fluid. The director member is configured on at least one internal wall of the enclosure and defines flow path of the coolant fluid so as to direct coolant fluid to thermostat and facilitate sufficient contact between coolant fluid and thermostat and the retainer member configured on the body is disposed around thermostat to prevent the coolant fluid from bypassing of the thermostat, thereby retaining coolant fluid in contact with thermostat to ensure precise sensing of temperature by the thermostat.

Abstract: An integrated exhaust gas after-treatment system for eliminating pollutants present in exhaust gases is disclosed. The integrated exhaust gas after-treatment system includes a Diesel Oxidation Catalyst (DOC)-Diesel Particulate Filter (DPF) assembly, a Selective Catalytic Reduction (SCR), a dosing module and a reducing agent supply system. The Diesel Oxidation Catalyst (DOC)-Diesel Particulate Filter (DPF) assembly is connected to an exhaust gas manifold of an engine and includes a canister for holding a Diesel Oxidation Catalyst (DOC) and a Diesel Particulate Filter (DPF). The Diesel Particulate Filter (DPF) is disposed downstream of the Diesel Oxidation Catalyst (DOC) and is spaced there-from. The Selective Catalytic Reduction (SCR) is disposed downstream of the Diesel Oxidation Catalyst (DOC)-Diesel Particulate Filter (DPF) assembly and facilitates elimination of NOx present in the exhaust gases by reduction of the NOx.
