Engine 6ISBe 300 Cummins for KAMAZ (6ISBe300)

Engine Cummins 6ISBe

The Cummins 6ISBe engine is a 4-stroke diesel engine with 6 cylinders arranged in a row, which is a rather unusual design solution for engines of this class. It is considered the quietest engine in the series.

Thanks to the improved Common Rail fuel system, fuel injection pressure does not depend on engine speed. This improves driving performance, reduces noise and improves cold engine starting. Also, thanks to this system, Cummins 6ISBe consumes less diesel fuel compared to analogues. The presence of a turbocharger significantly improves engine performance, increases power with economical fuel consumption.

In a number of design and technological solutions, the 6ISBe is similar to the previous generation Cummins “B” series engines. The letter "e" in the designation indicates that it is designed for Europe.

The cylinder block is a single cast structure, there are no liners, this is what affects the durability and comfort during operation. To increase power parameters, a VGT turbocharger is installed, which, in addition to its main function, helps save fuel when operating at full power.

Cummins 4ISBe Error Codes

• 111 - Internal failure of the ECM module. This DTC can only occur if there is a problem within the ECM. The ECM cannot be repaired.
• 115 - Malfunction of the camshaft position sensor. The ECM detects that the crankshaft position and camshaft position sensor signal inputs are connected in reverse order.
• 122 - Turbine pressure sensor malfunction. The ECM determines that the intake manifold pressure sensor signal voltage exceeds the calibrated value for more than 1 second.
• 123 - Intake manifold pressure sensor circuit - voltage below normal or short circuit. The ECM determines that the intake manifold pressure sensor signal voltage is less than the calibrated value for more than 1 second.
• 124 - High pressure in the intake manifold. This DTC becomes active when the intake manifold pressure exceeds the maximum permissible value for a given engine power rating.
• 131 - Gas pedal throttle malfunction. The ECM determines that the accelerator pedal position sensor signal voltage exceeds the calibrated value for more than 1 second.
• 132 - Low voltage detected in the pedal position sensor or accelerator lever circuit. An open circuit in the signal circuit, power circuit, or ground circuit of the accelerator position sensor in the wiring harness or connectors.
• 133 - High voltage detected in the remote control accelerator position sensor circuit. The remote control accelerator position sensor signal circuit is shorted to positive or to the +5 V power circuit.
• 134 - Low voltage detected in the remote control accelerator position sensor or pedal position sensor circuit. The remote control accelerator position sensor signal circuit is shorted to engine ground or the ground wire in the OEM wiring harness or sensor. There may be an open circuit in the signal circuit, power circuit, or ground circuit of the remote control accelerator position sensor in the wiring harness or connectors.
• 135 - Malfunction of the oil pressure sensor. If the fault code appears only in cold weather, wait until the oil warms up.
• 141 - Low signal voltage or open circuit detected in the oil pressure sensor circuit. The ECM determines that the oil pressure sensor signal voltage is less than 0.25 VDC for more than 16 seconds.
• 143 - Low engine oil pressure. The engine oil pressure sensor is installed on the left side of the cylinder block.
• 144 - High signal voltage or open circuit detected in the coolant temperature sensor circuit. The ECM determines that the coolant temperature sensor signal voltage is greater than 5.13 VDC for more than 1 second.
• 145 - Coolant temperature sensor faulty Engine coolant temperature sensor faulty. The signal circuit may be shorted to ground in the wiring harness or sensor.
• 153 - A high signal voltage has been detected in the intake manifold temperature sensor circuit. The ECM determines that the intake manifold temperature sensor signal voltage exceeds the calibrated value for more than 1 second.

Purpose

Relatively low price for a powerful all-wheel drive truck, low diesel fuel consumption, lightness, good cross-country ability and exceptional stability are the obvious advantages of trucks built on the KamAZ-43502 chassis. And at the same time – the secrets of their popularity in Russia and the CIS. This model is used both to staff the vehicle fleet of the Russian armed forces and in the civilian sector. In particular, shift buses of domestic oil and gas producing companies are often installed on the KamAZ-43502 chassis. These are SPTS - specialized cross-country passenger vehicles.

The ambulance, equipped on a KamAZ-43502 chassis and designed to operate in extremely difficult climatic and road conditions, was successfully tested on the Kolyma highway in the winter of 2022, covering 1,370 km from Magadan to a number of settlements and back. In extreme conditions, the driving performance of the car, the performance of autonomous heating and lighting systems, including at night, and the durability of the body and electrical equipment in difficult climatic conditions were tested.

The modern fire truck is built on a KamAZ-43502 all-wheel drive chassis. Its arsenal includes a tank for 3 thousand liters of water, a tank for 200 liters of foam, a pump with a capacity of up to 40 liters per second, a powerful compressor for supplying compressed air, an advanced fire extinguishing and smoke absorption system with Hiromax water mist, and space for a fire crew of seven people. Also, at the Army-2015 and Interpolitech-2015 exhibitions, the Patrol armored vehicle on the KamAZ-43502 chassis was presented.

Device

In KamAZ 43502, non-standard ideas and solutions developed by specialists of the Kama Automobile Plant were embodied. At the same time, the model retained the traditional advantages of the brand’s trucks.

The car is based on a 4 by 4 wheel arrangement and has all-wheel drive. The equipment is equipped with a classic spring suspension (front and rear). KamAZ 43502 has locking center and wheel differentials, which allows uniform torque to be transmitted to the axles and ensures their rigid connection and blocking. Due to this, the car easily overcomes difficult road sections. The wheel differential promotes uniform rotation of the wheels on the axle.

The car is equipped with a restyled all-metal cabin located above the engine. Modifications are available with and without a berth. The difference between the restyled version is its modern design and increased height. A modernized front panel is installed in the cabin. The brake and fuel pedals have been moved to a different location, and a tool compartment is located under the passenger seat. The driver's seat can be adjusted for backrest curvature, frontal movement and rigidity.

Cabin

The car is equipped with a restyled all-metal cabin located above the engine. If previously modifications of the KamAZ-43502 were produced both with and without a berth, now all vehicles of this model are equipped with a cabin with a sleeping bag. With the exception of cars for the Armed Forces of the Russian Federation. The difference between the restyled version of the cabin is its modern design and increased height. The interior has a modernized front panel. The brake and fuel pedals have been moved to a different location, and a tool compartment has been installed under the passenger seat.

The restyled cabin attracts three new individual seats that can be adjusted. The driver's seat has an air suspension that effectively dampens vertical vibrations. It reduces the load on the spine and reduces fatigue. The steering wheel, made of soft plastic, is adjustable in height by 8.5 cm and up to 15 degrees in tilt angle. This allows the driver to choose the optimal position and get comfortable behind the wheel. The gear shift lever, made of durable thermoplastic, is equipped with vibration dampers, which also increases operating comfort. All necessary machine controls are concentrated within arm's reach. The driver has at his disposal a new instrument cluster that provides quick reading of control parameters.

A Russian standard tachograph with a CIPF unit (Continental DTCO 3283) is now installed in the KamAZ-43502 cab. It accepts new driver cards. On the rear wall of the cabin of rotation buses based on KamAZ-43502 there are two viewing windows, with the help of which you can use gestures to transmit information to the passenger compartment (where there is also a viewing window). Internal communication is also provided through a transport intercom (TPU).
