Petrol Injection System for Natural Gas Engine Power and Longevity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bi-fuel vehicles running on natural gas face issues with power loss on uphill roads and in low ambient temperatures, leading to frequent switching to petrol mode, and suffer from engine depreciation due to dryness, which reduces engine life and increases fuel consumption.
Innovation Solution
A system that injects extra petrol into the engine when the accelerator pedal is pressed beyond a certain point, allowing simultaneous combustion of natural gas and petrol, enhancing power and reducing engine dryness, while avoiding petrol injection in traffic jams and downhill conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If natural gas is used as the sole fuel, then air pollution is reduced and fuel economy is improved, but engine power is insufficient for uphill roads and low temperature starting
Solution Approach 1:
The system merges natural gas and petrol into a dual-fuel configuration, allowing the engine to benefit from the pollution-reducing properties of natural gas while incorporating petrol to provide the necessary power boost during high-demand conditions such as uphill driving or cold starts
Solution Approach 2:
The system dynamically adjusts fuel composition by injecting petrol only when the accelerator pedal is pressed beyond a certain threshold, enabling the engine to adapt its power output to match driving conditions while maintaining low emissions during normal operation
2Use of energy by moving object
If natural gas is used as the sole fuel, then fuel cost is reduced, but engine life is shortened due to dryness-induced depreciation
Solution Approach 1:
The system applies partial petrol injection only when necessary (during high accelerator pedal depression), providing just enough lubricating effect to counteract the drying impact of natural gas without significantly increasing fuel consumption or cost
3Power
If petrol is injected continuously to maintain engine power, then engine power is sufficient for all conditions, but natural gas consumption increases and air pollution worsens
Solution Approach 1:
The system employs periodic or conditional petrol injection triggered only when the accelerator pedal is depressed beyond a predetermined threshold, rather than continuous injection, thereby maintaining engine power when needed while minimizing additional fuel consumption and emissions during normal cruising
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables bi-fuel vehicles to operate efficiently on natural gas in challenging conditions without switching to petrol, reducing natural gas consumption by 50% and minimizing air pollution, while extending engine longevity.
Implementation Method 1
Combustion of natural gas and petrol simultaneously, increase the power of the engine dramatically

AI summary
The invented system adds some petrol fuel to the vehicle engine which runs with natural gas (CNG or LPG). It causes a simultaneous combustion of petrol and natural gas (CNG or LPG). This action decreases depreciation of engine, increases power of the engine and reduces fuel consumption in natural gas vehicles. The above-mentioned system consists of an innovative petrol holder storage, an electronically circuit, a relay, a lever micro switch and a petrol fuel injector. Whenever the accelerator pedal is pressed more than a certain amount, the system will be activated and command to inject petrol collected in the storage into the air manifold.
