Daihatsu's geared diesel engines are employed in ferry boats, tankers, freighters, working craft and many other types vessels. Our marine engines are highly acclaimed all over as reliable propulsion systems.
Years of enduring R & D has made us tough and proud of our successful record and won us the trust of many faithful customers. Our search for progress and betterment continues with strong emphasis on reducing emissions of harmful substances.
Both the engine and shaft drive system are no longer operated in fear of critical revolutions when shifting from idle to rated rpm. The merits are well demonstrated in fuel-saving cruising at reduced speed. Moreover, thanks to our in-house developed doughnut RD coupling, we have eliminated the problem of torsional vibration. Now, customers are free to select shafting and propeller to suit their vessel's needs.
Our manufacturing plants are certified by JG, NK, LR, AB and CCS, moreover the famed ISO9001 for excellence in quality assurance systems. Thanks to this, the hi-tech and high quality we stand by are known worldwide.
Daihatsu Diesel has offices and dealers all over the world. We offer complete aftercare service and make every effort to communicate with customers.
The generator and cargo oil pump are driven by a crank shaft through the reduction gear and front engine block. This saves on space, reduces maintenance and offers other advantages.
Daihatsu's geared diesel engines were the first in the world to run on heavy fuel (H.O.7000 cSt/50°C). Moreover, they can run in the low-load region.
Adopting an exhaust gas economizer and hot effluent circulation system, waste heat energy is recovered and efficiently utilized as an onboard heat source to heat tanks, lines, living quarters, etc.
We have spared no efforts in shortening maintenance time and reducing the number of parts. As a result, maintenance and inspections are both simple and speedy for mid-speed engines.
Propeller revolutions can also be freely set. A larger diameter propeller and multiple-input gear system greatly boosts economy, sailing speed and tow-tug force.
Customers can freely select reduction gears and gear ratio to suit vessel usage. Furthermore, with additions like Daihatsu's CRASH ASTERN system, slipping control and 2-speed slip-clutch reduction gears, vessels can go smoothly and directly from full-speed to dead-slow ahead.
Our mid-speed engines have a low vibromotive force, resonate with vessel natural vibrations and are quiet. Furthermore, dynamic load is small and torque fluctuation minimized, making them advantageous.

Daihatsu's multiple-geared diesel engines are ideal for ships with twin-shaft propellers or low ceiling engine rooms. We offer a wide selection to choose including a twin-engine single-shaft system, single-engine twin-shaft system, four-engine twin-shaft system, four-engine single-shaft system and eight-engine twin-shaft system. Engine cut-off is also possible according to ship speed.
■ Single-Engine Twin-Shaft System for Double-Bow ShipsDaihatsu Diesel engines are at work onboard double-bow ships navigating narrow channels or short routes, or which operate as sightseeing boats on river cruises, etc. A single engine drives the propellers on the bow and stern. Any combination of single-engine twin-shaft system and Daihatsu's remote control system can be selected according to steering demands and guarantees improved navigation.

With the right size propeller, fuel consumption is reduced by as much as 3% in comparison with conventional propellers running at the same nautical speed, when propeller rpm is lowered by 10%. Daihatsu Diesel can set the propeller that best matches the vessel thus offering greatly improved propulsion efficiency.
CRASH ASTERN System
With a low-rpm large-diameter propeller, engine stalling is always a problem when moving astern because of increased torque and engine overload. For this reason, Daihatsu geared diesel engines employ our own CRASH ASTERN system. It can also be effectively operated from the bridge.
With Daihatsu's geared diesel engines, generators, cargo oil pumps and other machinery can be driven using power drawn through the front engine block and reduction gear. This system greatly reduces fuel consumption. What's more, one of the generators used in conventional systems can be omitted, which enables more effective use of dead space. In addition, this kind of system reduces labor and costs in running and maintenance. Also, engine and onboard control systems can be freely designed.
* Performance will vary according to ship speed, type of vessel and sea conditions.

Though low-speed and high thrust are necessary for port navigation, high-speed cruising performance is needed on the open seas. Our 2-speed reduction gear is ideal for the situation.We developed the 2-speed system (2-step ahead, 2-step astern) to maximize efficiency in normal and low-speed sailing. Because the reduction gear is suited to all kinds of vessels, from freighters to fishing trawlers, captains all over have favorably evaluated it.
Clutch fluid is electronically controlled to slip the clutch. As such, propeller revolutions below idling rpm are freely controlled.

Special speed-increasing/reduction gear
1. Enables dead-slow sailing ahead/astern with a fixed pitch propeller (FPP).2. Enables shockless, smooth clutch meshing.3. Propeller revolutions remain stable even under fluctuating engine revolution
and propeller load.
Features
1. An electronic governor keeps constant generator revolutions, thus ensuring a stable power supply.
2. Because of the 2-speed slipping clutch, the generator can operate a wide engine revolution range from idling to rated rpm.
3. Generator revolutions and droop can be adjusted easily during generator operation. Load switching to other generators and parallel operation can performed easily.
A compact constant-speed shaft generator is built into the reduction gear. Clutch fluid is automatically controlled by an electronic governor. By slipping the clutch, generator revolutions can be kept constant even under fluctuating engine revolution.

Advantages of Electric Propulsion
Ships
Electrical propulsion systems are different from the systems on conventional ships, where the propellers are turned directly by the main diesel engine; instead, the propellers are turned by an electric motor. This energy-saving, next-generation system covers economical, propulsion and safety demands.
This equipment consists of plural sensor units, inserted into crankcase side wall of each cylinder on diesel engine, and an integrated controller which controls sensor units by the communication link.Sensor units is compactly designed to detect oil mist by the natural diffusion system without air suction mechanism by moving parts like a fan, driving air, and piping, as well as, realizes improved reliability, and easy maintenance.Controller constantly monitors the oil mist density in the crankcase, and indicates the oil mist level. Additionally it will indicate status with alarm in case the oil mist density will be increased over normal level by overheated bearing etc, so can realize early detecting and reasonable precaution for the serious accident in a low-, medium-, and high-speed diesel engines.
Daihatsu Diesel Equipment for Marine Applications
Loading capacity is increased by reducing the size of the engine room. The engine room and propellers can also be optimally located to create the ideal hull form.
The use of a medium-speed engine allows vibrations and noises to be reduced. Compact, lightweight components also enhance work safety.

The Oil Mist Detector Monitors your engine to detect major engine failure.
Since 1976, Daihatsu Diesel Mfg. Co., Ltd. has put OIL MIST DETECTOR continuously on the market. In 2004, model MD-SX which is of sensor type mounted on crankcasewas developed. It can directly measure the oil mist density inside crankcase in a waythe sensor is so mounted that the sensing part is sticking into the crankcase.Conventional system has to take out oil mist for measurement from crankcase insidethrough piping.The new system provides following merits by the oil mist level is sent out for thecontroller as digital signal.
(1) Speedy response in less than 1 sec. with max. No. of sensor 16(2) Self diagnosis functions to display the time for sensor replacement
In recent years, as fire prevention measures for tankers, earlier detection on abnormaloil mist level in engine room is required as it is thought to be effective in pin-point the cause and its measures. Daihatsu Diesel Mfg. Co., Ltd. has further advanced MD-SX typedetector into OIL MIST MONITORING DEVICE, OMM type, whose development is based on thetechnologies of MD-SX type many classes give TYPE APPROVAL.The new OMM type can provide visual display on oil mist level where it is likely togenerate.The OMM type is expected to go into the market October, '07.
The system does not guarantee prevention of disaster, such as a fire.
