Arimitsu Industry Co., Ltd. (Headquarters: Osaka, Osaka Prefecture; President: Daiyu Arimitsu) announces the development of the 'TRY-880ESM-FI', a soundproof high-pressure washer equipped with a general-purpose gasoline engine with FI (Fuel Injection).
Since its founding in 1923, Arimitsu Industry has developed products with its core high-pressure pump technology, specializing in 'powerfully and finely controlling' water and air, providing products that support societal infrastructure in the industrial, environmental, and infrastructure fields.
This product is an industry first* in the domestic high-pressure washer market for a product intended for practical application and market launch as a soundproof high-pressure washer equipped with an FI engine.
*Appearance may differ from the actual product.
■ Development Background
While general-purpose engines with carburetor specifications are still mainstream in the high-pressure washer field, the transition to FI engines is progressing in other industrial machinery fields from the perspectives of startability, fuel management, and environmental compliance. Based on these technological trends, our company has undertaken the deployment of FI technology in the high-pressure washer field.
■ Environmental Consideration (Effects of the FI System)
The FI (electronically controlled fuel injection) system installed in this product improves combustion efficiency by electronically optimizing the fuel injection amount according to the engine's operating conditions. This helps to suppress unburned fuel and smoldering operation, which tend to occur during low-load and partial-load operation, and contributes to reducing unburned components in exhaust gas.
Furthermore, by suppressing wasteful fuel injection, a reduction in fuel consumption can be expected, which in turn leads to a reduction in CO₂ emissions. In addition, the configuration achieves a balance between consideration for the working environment and the environment, such as odor reduction due to less unburned gasoline and the elimination of the need to drain gasoline during storage.
■ Main Features
- Stable startability and combustion control with an FI (electronically controlled fuel injection) engine
- Optimized combustion over a wide operating range, including low-load regions
- Improved maintainability by reducing fuel management work during storage
- Main Specifications: Pressure 7.8 MPa, Flow Rate 28.7 L/min, Rated Output 5.5 kW (7.5 PS)
■ Market Launch
To stably provide this industry-first technological configuration, the initial lots will be rolled out as a phased introduction with the highest priority on stabilizing quality and supply systems.
Based on our manufacturer's responsibility to prioritize quality and reliability, we will be handling orders on a build-to-order basis for the time being.
In addition, we are currently proceeding with the procedures for registering this technology with NETIS (New Technology Information Provision System).
■ Annotation
*The term 'industry first' for this product is based on our own research, which found no confirmed cases of a soundproof high-pressure washer equipped with a general-purpose gasoline engine with FI (Fuel Injection) being commercialized for practical application and market launch in the domestic market. General-purpose engines with FI systems have been adopted in other fields.
