TRANSMISSION 1. A transmission or gearbox provides speed and torque conversions from a rotating power source to another device using gear ratios. The most common use is in motor vehicles, where the transmission adapts the output of the internal combustion engine to the drive wheels. Such engines need to operate at a relatively high rotational speed, which is inappropriate for starting, stopping, and slower travel. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process.. While a differential may also provide gear reduction, its primary purpose is to change the direction of rotation. Many manual transmissions include both synchronized and unsynchronized gearing; it is not uncommon for the first/reverse gear to lack synchros. Those gears are meant to be shifted into only when the vehicle is stopped. 2

The engine room is one of these spaces, and is generally the largest physical compartment of the machinery space. The engine room houses the vessel's prime mover, usually some variations of a heat engine - diesel engine, gas or steam turbine. On some ships, the machinery space may comprise more than one engine room, such as forward and aft, or port or starboard engine rooms, or may be simply numbered. 1.1)Main engine The engine room of a motor vessel typically contains several engines for different purposes. Main, or propulsion engines are used to turn the ship's propeller and move the ship through the water. They typically burn diesel oil or heavy fuel oil, and may be able to switch between the two. There are many propulsion arrangements for motor vessels, some including multiple engines, propellers, and gearboxes. Large engines drive electrical generators that provide power for the ship's electrical systems.
the explosion. This means that it can't create as much power when it's ignited by the spark plug. For a supercharger to work at peak efficiency, the compressed air exiting the discharge unit must be cooled before it enters the intake manifold. SUPERCHARGERS There are three types of superchargers: Roots, twin-screw and centrifugal. The main difference is how they move air to the intake manifold of the engine. Roots and twin-screw superchargers use different types of meshing lobes, and a centrifugal supercharger uses an impeller, which draws air in. Although all of these designs provide a boost, they differ considerably in their efficiency. Each type of supercharger is available in different sizes, depending on whether you just want to give your car a boost or compete in a race. Supercharger Advantages The biggest advantage of having a supercharger is the increased horsepower. Attach a supercharger to an

Most types of truck air brakes are drum units, though there is an increasing trend towards the use of disc brakes in this application. The compressed air brakes system works by drawing filtered air from the atmosphere, compressing it, and holding it in high-pressure reservoirs at around 120 PSI. When needed for
Compression will raise the air temperature and a charge air cooler is fitted to reduce the temperature of the air between the turbocharger and the engine inlet manifold. The cooler consists of a tube stack of aluminium brass tubes rolled and solder-bonded into two brass tube plates. Cast iron water boxes attached to the tube plates and allow salt water circulation within the tubes to make two passes. MEASURING TOOLS There are a lot of different tools on board ship, which are used for doing special jobs. All the tools can be classified as follows: a) measuring tools; b) cutting tools; c) marking tools; d) hand tools; e) hydraulic tools; f) electric tools; g) pneumatic tools. This chapter will describe measuring tools. Ruler is a long narrow flat piece of hard material with straight edges, marked with
ix Introduction Modern electronic systems are increasingly digital: digital microprocessors, digital logic, digital interfaces. Digital logic is easier to design and understand, and it is much more flexible than the equivalent analog circuitry would be. As an example, imagine trying to implement any kind of sophisticated micro- processor with analog parts. Digital electronics lets the PC on your desk execute different programs at different times, perform complex calculations, and communicate via the World Wide Web. While the electronic world is nearly all digital, the real world is not. The temperature in your office is not just hot or cold, but varies over a wide range. You can use a thermometer to determine what the temperature is, but how do you convert the temperature to a digital value for use in a microprocessor- controlled thermostat? The ignition control microprocessor in your car has
