The trend in the engine and genset industry is the development of electronically controlled engines and the standard of integrated controls is getting better.
Cummins believes it is keeping ahead of this trend with a range of gensets that are fully electronically controlled as well as being environmentally friendly. By implementing innovative engine modifications and after treatment technologies, Cummins has found an answer to consumers’ key demand for cleaner energy.
A major thrust to meet this demand is the design and introduction of full authority (electronically controlled) engines and gensets. This extensive range of gensets is set to grow further in coming years as further developments are introduced.
The advantages of developing full electronically controlled engines and generators are numerous and include the ability to optimize the system to the user’s specific application. Fuel economy, emissions, noise levels and power density can all be monitored and controlled through advanced digital instrumentation.
The new ISB engine powered gensets are a result of the Cummins Euro 3 project, which was established to develop industry-leading engines from 3.9 to 11 l that exceeded all current emission legislation.
The gensets, to be launched between the 100-250 kVA nodes, surpass other sets in this range in terms of power density, torque and fuel efficiency. In addition, the common rail fuel system that they utilise helps to optimize engine parameters such as emissions and fuel efficiency.
The new QSK23 genset models, launched in the second quarter of 2003, are designed to replace the QST30G1 and QST30G2 with a more advanced and cost effective alternative. They have higher power density while still being TA Luft and EPA Tier I and Tier II emission compliant.

New engine milestone
Around 40 of MTU’s 20 V 4000 genset engines have been sold since its launch last year. Seven of the models were sold to a Germany-based software company. The company uses them to assure the supply of emergency power to its data centre. Each of the gensets has an output of 2875 kVA when required.

As from next year, the models will be used for supplying emergency power to the firefighting pumps on the Kristin drilling rig. The scope of supply includes the complete gensets with an electrical power 3300 kVA, as well as the cooling and exhaust systems. The installation is the first offshore application for 20 V 4000 engines.
New engine with developed electronics
Volvo Penta now offers electronic diesel control for its four, five, six and 7 l industrial engines for all types of applications. The system known as EDC 4 is a refinement of Volvo Penta’s electronic diesel control. EDC 4 is available in two designs. The first design is suited for installation in vehicle systems using CAN-Bus technology according to the J1939 standard. The other is regulated with a traditional potentiometer and is suitable for installation in applications with mechanical control.
EDC 4 offers major possibilities to adapt each engine after the application’s requirements. Volvo Penta, or the customers themselves, can simply adjust a number of different parameters.

Volvo Penta is launching Vodia, a tool for diagnosis and service. Vodia looks like a handheld computer and is easy to use. Data and results from all tests, fault detection, diagnoses etc, are presented in text and clear graphics that the tool can secure from the engine. It can also be used to adjust a number of parameters in the engine.
Waukesha adds VGF extender
Waukesha Engine has announced the launch of its Extender package to its popular VGF engine line.
The Extender package, which is standard on all VGF engines manufactured from April 2003, offers internal enhancements that increase the engine’s durability. The most visible feature of the new Extender package is the new oil pan that has twice the capacity of the previous pan. Besides lengthening the period between oil changes, the pan has access panels to allow servicing of major engine components (oil pump, main and rod bearings) without having to be removed. The wider, heavier pan also reduces vibration and serves as a base for the six and eight cylinder engines.
The Extender package is designed to enhance engine durability
Doubling the oil capacity is just one of the improvements now standard with the Extender package of VEE and in-line VGF engines. Reliability advancements were also made to engine’s top end that include:
- Improved valve train lubrication to significantly reduce wear.
- Polished chrome stem valves reduce guide wear and promote longer life.
- Closed breather system element with integral vacuum regulator maintains negative crankcase pressure to prevent oil leaks.
