The first refinement in crankcase ventilation was the road draught tube. This is a pipe running from the crankcase (or the valve cover on an overhead valve engine) down to a downwards-facing open end located in the vehicle's slipstream. When the vehicle is moving, airflow across the open end of the tube creates suction (a "draught" or draft ...
In 2012, a "Technical Update" was applied to the N63, resulting in the N63TU variants (also known as N63B44O1).The main upgrade was the addition of Valvetronic. [11] [12] Other changes include revised turbochargers, removal of the blowoff valve, lighter pistons, forged connecting rods and crankshaft, addition of a valve cover labyrinth oil catch/return system, new valve stem seals, revised ...
A crankcase is the housing in a piston engine that surrounds the crankshaft. In most modern engines, the crankcase is integrated into the engine block. Two-stroke engines typically use a crankcase-compression design, resulting in the fuel/air mixture passing through the crankcase before entering the cylinder(s). This design of the engine does ...
The vent/rollover valve provides a method of controlled escape for gasoline vapors during the refueling process. It has a mechanism which closes the vent in the event the vehicle rolls over, to prevent spilling of VOCs or fuel in general. It also acts as a fill limiter. [8] [dead link ]
Manifold vacuum, or engine vacuum in a petrol engine is the difference in air pressure between the engine's intake manifold and Earth's atmosphere.. Manifold vacuum is an effect of a piston's movement on the induction stroke and the airflow through a throttle in the intake manifold of an engine.
The crankcase heater keeps refrigerant at a temperature higher than the coldest part of the system. A crankcase heater generally has the same electrical symbol as a resistor because it converts electricity directly into heat via electrical resistance. The resistance in the heater coil determines the heat it produces when voltage is applied. [1]
The Turbo-back (or turbo back) is part of the exhaust system from the outlet of a turbocharger to the final vent to open air. Turbo-back systems are generally produced as aftermarket performance systems for cars with turbochargers. Some turbo-back (and header-back) systems replace stock catalytic converters, while others have less flow restriction.
The 1978–1979 Li'l Red Express truck used a special high-performance 360 4-barrel engine with factory production code EH1 that was rated at 225 SAE Net HP in production form [5] The EH1 was a modified version of the E58 360 police engine (E58) producing 225 hp (168 kW) net at 3800 rpm due in part, that as it was installed in a "truck", and ...
