Spark & Diesel Engines

bDynamically Variable Stroke Technology” (DVST) applied to

Spark Ignition and Diesel engines.

Using our  DVST can make existing technology viable without complicated crank and connecting rods or Variable Valve Timing (VVT).


 Designs have been developed by our designer to demonstrate how to convert existing units.These designs and many others are available for customers to use as reference material.

The Dynamically Variable Stroke Technology is designed to be of use to various designers and manufacturers.

A full set of design drawings and marketing presentations is available.

When applied to internal combustion engines DVST allows the compression ratio to be varied while the engine is running.

Dynamically Variable Stroke Technology as applied to

Multicylinder Applications –

Dynamically variable Stroke Technology applied to Spark Ignition Engine Technology (SPE)

Homogeneous Charge Compression Ignition (HCCI) (known to give 25% reduction in fuel consumption and reduced greenhouse gases, global warming and pollution).

Variable Compression Ratio (VCR) (Used for changing fuel types and performance)Alternative fuels with this technology are many – mineral and vegetable based fuels can be considered (if lubrication oil matches the fuels used). Vast improvements in the transport of goods using different fuels can be invisaged. 

VCR also effects the capacity, hence size of the engine depending on its power requirement.

Note! HCCI and VCR technology is owned be others however Dynamically variable Stroke Technology allows these to be used in a production situation.

Diesel Engines (DE) Homogeneous Charge Compression Ignition (HCCI) (known to give a reduction in fuel consumption and reduced greenhouse gases).

Variable Compression Ratio (VCR) (used for changing fuel types)

Large Diesel engines – ships as illustrated – have fuel savings which effect transport of goods around the world!


Some of the many applications include: Prime movers,  trucks, buses, aircraft, cars, mining trucks, tractors, propeller airplanes. Manufacturers of any of these examples can use our technology to increase  their product marketability.
