148100 - The Synergistic Engine System Operation 

Abstract: 

Introduction

Internal combustion (IC) engines, whether operating in a hybrid or alone, will remain the dominant source of power in automobiles for the foreseeable future.  The automobile industry continues to face increasingly restrictive fuel economy regulations and lower emission regulations.  To meet these requirements engines will continue to get smaller.  Additionally, the Proposed EPA 2027 regulations greatly eliminate the use of enrichment, previously used to aid vehicle performance in transient modes.  The industry needs a cost effective solution.

The Challenge

It is currently technically possible to meet these requirements, but resulting vehicle performance would be completely unacceptable.  These engines will exhibit reduced power, poor vehicle launch, and drive quality issues.  Current solutions to these problems require “add on” systems, which are very expensive, present significant packaging issues and only partially address problems.

The Synergistic Engine System (SES)

The Synergistic Engine System Technology: improves engine tip-in response, eliminates perceptible turbo lag, improves engine efficiency, and is adaptable to current engines without modifying the existing power head.  The SES Technology can also substantially mitigate performance problems that result from eliminating “enrichment” as required by the Proposed EPA 2027 regulations.

The SES accomplishes this through a unique combination of proven concepts.  These are:

1.     Throttle valves - positioned near the intake ports on each cylinder in the engine, minimizing the volume of low pressure air between the intake valve and throttle, improving initial charge density and resulting in 80-90% reduction in time to torque.

2.     Equalization ports - evenly distribute air between cylinders, can be used to operate idle smoothly, and reduce pumping losses during deceleration and part-throttle operation.

3.     Equalization valves - can be added to these ports to enhance control in various engine operating modes.

Synergistic Engine System Application

The SES Technology adapts to a wide variety of engine configurations without requiring changes to combustion components, such as:

·      Multiple cylinder engines with single or dual intake ports

·      Turbocharged or naturally aspirated engines

·      Hybrid or IC engine only powerplants  

The SES Technology is protected by 10 U.S. utility patents; 7 addressing the SES apparatus and methods generally, and 3 addressing utilization of equalizing port(s) and valve(s).

The Synergistic Engine System makes smaller, lower emission engines perform like Big Engines.
