Overview

Driving the transition to sustainable fuels.

While traditional diesel engines have helped power the industrial world for over a century, our Modular Linear Generator (MLG) is designed to address modern challenges, and become the industrial generator of choice for the next century.

The heart of the Modular Linear Generator is the CAVIE™ module. Our CAVIE™ modules use up to 40% less fuel with diesel, thanks to our patent pending combustion chamber architecture and highly variable piston and valvetrain control. These same features enable CAVIE™ modules to switch fuel types on-the-fly, and efficiently run with combination fuels. Our generators will ease the transition to more sustainable fuel types (such as natural gas, biofuels, synthetic fuels, hydrogen), and protect customers from fuel price fluctuation by offering unprecedented fuel choice for generators.

CAVIE™ modules are designed for up to 25kW output from a single module and can be stacked together in a single enclosure for higher power outputs, up to 2MW. For customers interested in generator power beyond 2MW, a CAVIE™—L module with single module output up to 500kW can effectively serve needs of 10MW+.

Pre-orders for MLG systems are available now. Don’t miss out on the financial savings and fuel security of an MLG system for your power generation needs.

Technology

Continuously Adaptive Volume Intelligent Engine (CAVIE™)

 

CAVIE™ modules are the heart of the modular linear generator. Conventional engine technology has a limited ability to adapt to changing conditions and loading demands; therefore, efficiency in real world use suffers. CAVIE™ modules can adjust key physical parameters of the generator (displacement, compression, valve lift and timing, fuel injection) to maintain high combustion efficiency across a wide range of loading. Multiple CAVIE™ modules can be combined together for higher maximum output, and even greater load matching capability as individual modules can deactivate completely when not needed.

How are CAVIE™ modules so efficient?

Eliminate rotating component friction.

In a common diesel engine, 10-15% of energy is wasted in mechanical friction. The MLG is a linear engine, meaning combustion energy is converted into electricity directly through linear electric generators. This engine layout eliminates most frictional components in an engine, including crankshaft, connecting rods, camshafts, and rocker arms.

opposed piston icon.jpg

Most engines have a single piston per cylinder and a combustion chamber enclosed by a cylinder head. An opposed piston engine has two mirror image pistons sharing a cylinder. Effectively a cylinder head is replaced by another piston, which can extract more useful work from combustion instead of thermal loss. Additionally, two pistons per cylinder allows for lower piston speeds and higher combustion efficiency.

4-stroke combustion cycle.

While opposed piston engines offer significant efficiency gains, it becomes difficult to include valves required for an efficient 4-stroke combustion cycle. Intelline's patent pending piston-centric valves allow us to combine the benefits of an opposed piston engine with a 4-stroke cycle in a simple and compact package.

The MLG linear engine is not constrained by a traditional crankshaft and connecting rods, and with our Intelline Reconfigurable Linear Electric Motors (RLEMs) the MLG can actively vary its displacement to efficiently match power output to the demands of the load. Furthermore, our pneumatically actuated valvetrain offers full timing and lift control, for optimal flow in varying conditions.

Lower parasitic losses.

The higher thermal efficiency of the MLG reduces demands on supporting components. For example, lower heat rejection allows a smaller and more efficient coolant pump. Lower fuel consumption also reduces fuel pump demands. Additionally, the MLG is a virtually oil-free engine, negating the need for an oil pump (and oil changes!)

Load Matching

CAVIE™ modules can adjust displacement, compression, valve timing, and more on the fly, to maintain high combustion efficiency even at low loads.

Flexible Fuel Options

The ability to adjust displacement and compression allows multi-fuel equipped systems to switch fuel types at any time. The CAVIE™ architecture makes it easy to retrofit new fuel systems in the future as well.

Low Maintenance 

CAVIE™ modules use a pressurized air bearing system instead of traditional oil lubrication, allowing for longer operating time between routine service.
