The upper part of the valve stem, within the rocker box, is lubricated by oil. If this oil travels unchecked along the valve stem, engine HC emissions will become excessive. To control this, an elastomeric seal is fitted over the top of the valve guide. These may wear or stiffen with age, so are usually replaced whenever valves are removed for ...
The 2.5-litre 6G73 is a 24-valve SOHC design with two valves running off a single cam lobe on the exhaust valves using a forked rocker arm and each intake valve actuated with two cam lobes, with a smaller bore than the 3.0L version of the same block. Bore and stroke are 83.5 mm × 76 mm (3.29 in × 2.99 in); it is a 60-degree V6 and weighs ...
The normally closed valves will not permit flow from the inlet port of the valve to the outlet port, normally the flow will be permitted only by changing the position of the valve. In general, valves are designated as 2/2 DCV, 3/2 DCV, 5/2 DCV, 5/3 DCV etc., in which the first number indicates number of ports and second number indicates number ...
[1] [3] [5] [6] The drivetrain was a repeat of that in the Mack NO, with a Mack TRDXT72 5 speed transmission with the transfer case mounted solidly to the rear of the transmission. This transmission was direct in 5th. The transfer case had a 2.50:1 low range, engaged the front axle, and had a power take-off to operate the winch(es). [3] [1] [7] [8]
Lap is the amount by which the valve overlaps each port at the middle position of each valve. [3] There are two different types of lap. The first kind is the steam lap, which is the amount by which the valve overlaps the steam port on the live steam side of the piston or slide valve (i.e. the distance the valve needs to move to just begin to ...

[2]: 8 Human intervention is required for the starting and stopping of the engine. Starting is challenging for several reasons: Initially the cylinder is cold and there is no vacuum in the condenser. [2]: 8 This has to be built up by a combination of the engines own air pump and several cycles of the piston replacing the air with steam. Then ...
