Many of our vehicles are not currently on display due to the Fonterra Science Roadshow exhibition on at MOTAT from 3 – 18 July. However, we will have a brand new vehicle display at our Great North Road site after the school holidays! MOTAT Road Transport has some spectacular events throughout the year such as classic car shows and car club days.
Galaxy of Cars Each year in February, MOTAT plays host to its flagship event, the Galaxy of Cars. This includes a brilliant car display that brings out some of the finest automobiles ever made. The Galaxy of Cars is always a huge success with entertainment for all ages throughout the day. MOTAT would like to thank the New Lynn Lions Club for the support in this running this massive event .
Prices: $10 adults, $4 children over 5yrs
-
cash only.
Shepherd Engine The “Shepherd Engine,” created by Gray Shepherd, inverts the core motion of the combustion engine. It features fixed pistons and reciprocating cylinders converting linear motion into rotary motion without the use of a crank shaft.
Fully balanced Shepherd Engine with lever assembly
In a conventional engine the majority of the power is harnessed from the combustion cylinder using inefficient techniques for pressure conversion and establishing physical leverage. At the top of the piston stroke, where gas pressure is highest, force transfer efficiency is at its lowest, though it rises as the piston descends and the connecting rod’s leverage increases. Peak efficiency happens about 40% through the piston stroke, then drops at an exponential rate that mirrors its rise. In addition, the piston doesn’t travel a path that is strictly parallel to the bore, so an angular force is transferred to the cylinder wall. This increases friction, wear, and fuel consumption.
The size of the torque output in the Shepherd engine is not limited by the physical radius of the crank shaft journal where it is attached to the connecting rod, and the engine is able to extract power efficiently form the reciprocating sleeve over a greater range of the power stroke. The result is the production of more torque for a greater period of time. Thus greater more uniform torque is generated which dramatically improves the engines ability to harness energy from the combustion event occurring inside the cylinder.
You can see a prototype of this amazing new concept during your visit to MOTAT!
