EiShin Co., Ltd.

eco-SPRAY : Energy Efficient &  
Eco-Friendly Automobile Filter Spray to Increase Mileage and Reduce Emissions

Eco-SPRAY is one of the environmentally friendly products manufactured by EiShin Co., Ltd., whose mission is to care for nature, humanity, plants and animals. Like most additives claimed to improve car performance, eco-SPRAY cleans the engine. It allows cleaner combustion which translates into improved power and fuel efficiency as well as reduced emissions. The spray can be applied through a filter from cars powered by gasoline, diesel or LP gas. Since 2012, 300,000 bottles have been distributed in 15 countries including China, India, Canada, USA, UAE, Korea, Cambodia, Vietnam, Iran, Philippines, Sri Lanka, Bangladesh, Nepal, Taiwan, and Japan.

Major Features and Advantages

I. Made of 100% Natural Ingredients

eco-SPRAY is made of 100% natural ingredients. No hazardous or artificial chemicals are added. It is, therefore, non-toxic and does not leave any damage to cars after use.

II. Easy Application

%ef%bc%92eco-SPRAY is easy to apply. No preparation is required. To apply, simply remove a filter from a car engine and spray a whole bottle (30cc) through the filter. Leave it for 15 minutes until it is dry before putting it back in the car. The use of eco-SPRAY is recommended every 5,000km.

III. Deep Cleaning

eco-SPRAY is extremely effective in deep cleaning car engines. It removes carbon deposits from the carbon combustion chamber, cylinders, pistons, and valves. What is unique about eco-SPRAY is that it changes the fundamental chemistry of combustion. It improves how the engine uses its fuel. Eco-SPRAY breaks up the water molecules in the air entering the engine and turns them into hydrogen gas and negatively charged ions. The hydrogen gas boosts combustion while the negatively charged ions neutralize the static built up in the engine for improved fuel flow. This mechanism helps the engine to run more smoothly and to idle smoother and quieter.

IV. Reduce Emissions

Incomplete combustion results in harmful gas emissions. With eco-SPRAY, harmful gas emissions are greatly reduced. A study conducted by the Japan Automobile Transport Technology Association (JATA) demonstrated that eco-SPRAY immediately reduces the emissions of carbon dioxide (CO), hydrocarbons (HC), and nitrogen oxide (NOx) by 30.4%, 23.3%, and 15.09%, respectively.

V. Improve Fuel Efficiency

Normally, 95% combustion is considered high. eco-SPRAY increases combustion efficiency to 95 to 100%. This contributes to better mileage, meaning less stop at the gas station is required.

eco-SPRAY improves car performance by effectively cleaning the engine for better combustion efficiency. It provides more power and mileage. It also saves the environment by reducing harmful emissions.



Technology Data

Conceivable applications

We contribute to save the earth by distributing eco-friendly products. Presently, we have our first product, “eco-SPRAY,” which improves the combustion efficiency by rendering the incoming air in the automobile engines more combustible by subdividing groups of molecules in the air. The eco-SPRAY is applied to car air filters every 5,000 km to reduce harmful emissions and increase gas mileage, typically from 8-40%, while decreasing air pollution.


%ef%bc%92Competitive advantage

  1. Made with only natural materials

Our company’s mission is to care for nature, humanity, plants and animals, and we strive to solve environmental problems by delivery of our eco-friendly products. The eco-SPRAY is made of 100% natural ingredients with no hazardous or artificial chemicals added. It is also non- toxic and will not cause any side effects to the cars after use.

  1. Improve Fuel Efficiency/Gas Mileage

One bottle of eco-SPRAY (30ml) applied to the car air filter every 5,000 km can improve gas mileage up to 8-40% and reduce fuel consumption.

  1. Reduce Emissions/Exhaust fumes

Tests results show immediate reductions of CO, HC and NOx gases typically ranging from 15-30%

  1. Increase Car Engine Power

Improved engine power up to 5-10% and smoother, quieter engine idling.

  1. Clean Car Engine

Deep cleaning of carbon deposits from car engine for efficient operation.

  1. Easy to use

No preparation is required prior to use. Simply remove the car air filter, apply a bottle of eco-SPRAY to the filter, let it dry and re-fit the filter.
