KDI TCR-MP

Product catalog summary

Overview: The document provides detailed specifications and features of the KDI Marine Propulsion engines, specifically models KDI 1903TCR-MP, KDI 2504TCR-MP, KDI 1903M-MP, and KDI 2504M-MP. These engines are designed for marine applications, offering a range of power outputs from 40.8 to 74 horsepower.

Engine Specifications: All models are 4-stroke diesel engines with inline cylinders, liquid cooling, and 4 valves per cylinder. They feature a camshaft in the crankcase driven by a gear train, with pushrod-rocker arms timing and hydraulic tappets. The engines have a cast-iron crankcase and cylinder head, and a closed crankcase ventilation system.

Technical Features: The KDI 1903 models have 3 cylinders with a bore of 88 mm and a stroke of 102 mm, resulting in an engine displacement of 1861 cm³. The KDI 2504 models have 4 cylinders with the same bore and stroke, leading to a displacement of 2482 cm³. Both models use direct injection systems, with the TCR models using a common rail system and the M models using a mechanical rotary pump.

Performance: All engines comply with EU RCD STAGE2 emission standards. The KDI 1903TCR-MP delivers a maximum power of 56 Hp at 2600 rpm and a torque of 225 Nm at 1500 rpm. The KDI 2504TCR-MP offers 74 Hp at 2600 rpm and 300 Nm at 1500 rpm. The KDI 1903M-MP provides 40.8 Hp at 2600 rpm and 133 Nm at 1500 rpm, while the KDI 2504M-MP delivers 50 Hp at 2600 rpm and 170 Nm at 1500 rpm.

Physical Characteristics: The dry weight of the engines without gear ranges from 240 kg for the KDI 1903M-MP to 323 kg for the KDI 2504TCR-MP. All models have daily service points accessible from one side and auxiliary PTOs with a maximum torque of 100 Nm.

Standard Equipment: Each engine comes with a Digital Deluxe-panel, electric starting system, oil extraction pump, 100Nm PTO facility, exhaust mixing elbow, fresh water expansion tank, and a front-mounted sea water pump. The alternator specifications vary between models.

Accessories on Demand: Optional accessories include flexible engine mounts, a hot water take-off kit, a second station harness and panel, and an oil pressure sensor for the Digital Deluxe-panel.

Performance Curves: The document includes performance curves according to ISO 14396, illustrating power and torque outputs under specified conditions. Power ratings are based on engines equipped with standard components and operating at ambient conditions of +25°C, 30% relative humidity, and 1 bar pressure. Power decreases by 1% per 100 m altitude and 2% per 5°C above +25°C.

Additional Features: The Deluxe Panel includes analog instruments for water temperature and oil pressure, with parameters such as RPM, voltmeter, hour counter, cooling water temperature, and oil pressure (on demand). Alarms are set for high fresh water temperature, low oil pressure, alternator charge, and service intervals.
