日本エンジン List of Products and Services

Japan Engine is participating in Aichi Prefecture's "Circular Economy Promotion Plan (10-year plan starting from 2022)" and is working on the circular economy. Japan Engine is a rebuilt automotive engine company with 75 years of history. "Rebuilt" refers to the process of disassembling, processing, cleaning, replacing parts, assembling, and inspecting used machinery to restore it to like-new condition. In the circular economy, an important aspect alongside regeneration technology is the establishment of channels for resource circulation. The traditional recycling economy is an economic activity focused on "repairing and regenerating when broken," which has proven inefficient due to the inability to standardize regeneration processes, resulting in the prioritization of "mass production and mass disposal" as the "efficient" economic activity. By collaborating with manufacturers and large users, a more efficient resource regeneration system can be established, contributing to the circular economy's environmental goals. Our company has also obtained SBT certification and believes we can help reduce CO2 emissions across the entire supply chain (clarifying the amount of reduction). If you are considering the circular economy, please feel free to contact us.

• Specially equipped vehicles

Company A, a steel manufacturer, was using special vehicles to load large steel materials onto transport ships. Due to the aging of these vehicles, Company A requested the overhaul of core components such as engines from a special vehicle manufacturer. However, since the vehicles were custom-made, replacement parts for the overhaul had to be newly manufactured. Therefore, Company A wanted to continue using the old vehicles while considering both cost and environmental aspects, and consulted with us. The repairs and overhauls we perform not only involve replacing parts with new ones but also allow for the restoration of old parts through polishing, buildup, and disassembly repairs, making them as good as new. [Case Study] ■ Consultation Details - The engine and all components are custom-shaped due to being a special vehicle. - The manufacturer suggested replacing the entire vehicle. ■ Proposal Details - Restore old parts to like-new condition through polishing and buildup. *For more details, please refer to the PDF document or feel free to contact us.

Company B, a major transportation company, has an in-house vehicle maintenance department that services its own trucks. Company B was purchasing rebuilt products for maintenance from multiple parts suppliers, but buying from different vendors each time led to increased labor and management costs, which ultimately raised expenses. They consulted with us regarding this issue. Our company not only sells rebuilt products for auxiliary equipment but also offers engine repairs and overhauls. Therefore, we assist with specialized engine repairs and overhauls that cannot be handled by Company B's maintenance department as needed. [Case Study] ■ Consultation Details - Although they were purchasing rebuilt products at low prices from multiple companies, planning maintenance became difficult, resulting in higher costs. ■ Proposal Details - We can provide a one-stop solution for not only rebuilt products but also engine repairs and overhauls, reducing both effort and costs. *For more details, please refer to the PDF document or feel free to contact us.

Company D, which operates a railway business, has a subsidiary for vehicle maintenance where vehicle maintenance was conducted. However, due to a strategy of selection and concentration in its business, it aimed to focus management resources on customer service and considered outsourcing part of the vehicle maintenance operations (such as door opening and closing equipment, excluding main power). With many transactions involving public transportation such as railways and buses, as well as major steel and electrical manufacturers, we were chosen for our confidence in technical and quality aspects, as well as our well-equipped inspection equipment and established reporting system for work content. [Case Study] ■ Consultation Details - In the railway business, where regular inspections and repairs are mandatory, we want a reliable outsourcing partner. ■ Proposal Details - In addition to technical and quality aspects, we also have a well-established inspection and reporting system. *For more details, please refer to the PDF document or feel free to contact us.

In engine rebuilding, it is said that approximately 80% of CO2 emissions can be reduced during the production process compared to producing new engines. Additionally, by reusing products instead of disposing of them, further reductions in supply chain emissions can be achieved. We encourage you to consider using rebuilt engines, not only to achieve CO2 reductions through "energy saving" and "cost reduction" in the new engine production process. *Source: Japan Society of Mechanical Engineers, "Effect of CO2 Emission Reduction by Using Rebuilt Engines," November 2018, Meiji University & Japan Automobile Recycling Business Association.

In Japan, since the Great East Japan Earthquake, large-scale earthquakes have been frequent. The effects of global warming have caused significant damage from typhoons and heavy rainfall, increasing the importance of disaster preparedness. Companies are also finding it essential to develop business continuity plans (BCP). School gymnasiums and martial arts dojos are not only introducing air conditioning as measures against extreme heat and heatstroke, but they also serve as evacuation centers during disasters. Therefore, establishing a system to secure energy during disasters (such as power outages) has become an urgent issue. In recent years, power-independent GHPs that can provide not only air conditioning but also emergency power and cooking energy during disasters have been spreading, and the installation of disaster response bulk (disaster response bulk) has also been increasing. By properly maintaining the engines of GHPs, we aim to enable effective use during disasters, and furthermore, by rebuilding aging engines, we hope to contribute to environmental protection through resource recycling and cost reduction for our customers.

With the spread of as-a-service models such as Mobility as a Service (MaaS), businesses are transitioning from a business model where they sell products outright to customers (users) to one where they retain ownership of the products and provide them to customers through sharing or subscription. In as-a-service models, the utilization rate of products increases, making proper maintenance key to extending product lifespan and utilizing remanufactured (rebuilt) products for cost reduction. Additionally, since businesses can manage the entire lifecycle of the products, they can contribute to a resource-circulating society by reducing waste through the use of remanufactured products.

• Vehicle Management System

Having specialized technicians in the in-house maintenance department of a railway company and performing maintenance on all parts is challenging in terms of management and cost. Additionally, there is a growing issue of a shortage of technicians in various fields, leading to an increase in companies that find it difficult to handle these tasks in-house even if they want to. Therefore, by outsourcing the maintenance of hydraulic components entirely, we can solve management and personnel issues, allowing companies to focus on the work that should be enhanced. Since safety and security are our top priorities, we are equipped with various testing machines specifically for railway components and have a thorough quality control system in place, so you can trust us to handle it with confidence.

• Other resource recycling

At Japan Engine, we have implemented a stock sales system for rebuilt products so that we can deliver them immediately when customers make inquiries. By delivering parts to customers and collecting the replaced parts, we create the next rebuilt products based on those parts. All rebuilt products undergo inspection using dedicated testing machines, and only those that meet our standards are delivered as rebuilt products.

Gas heat pumps (GHP) / generators / air conditioning systems, commercial air conditioners / freezers, etc., are mostly under maintenance contracts between end users and electrical manufacturers. While some manufacturers may handle everything in-house, managing all parts' maintenance in-house can be costly in terms of human resources. The engine, in particular, is one of the more complex parts with many components. There may be customers who can manage other smaller parts themselves but find the engine challenging. In such cases, please leave it to Japan Engine. As professionals in engines, we can take care of the engine portion of your maintenance contract through outsourcing. We have the largest facilities in the country for companies that perform overhauls, so you can trust us with regular overhaul contracts for dozens of units per month.

In recent years, instead of replacing diesel engines in large vehicles like trucks with new ones after a certain period, it has become increasingly common to revive them to like-new condition through regular maintenance and overhauls, allowing one engine to be used for a long time. An overhaul (OH) is an environmentally friendly method that involves disassembling an engine that has been used for many years and is starting to show operational issues, or one that has stopped working for some reason, down to the individual parts. It includes replacing and processing consumables and components, and then reassembling the engine to restore it to like-new condition. This process repairs the areas of friction to prevent air and oil intrusion or leakage, and cleans out sludge and carbon that have accumulated inside the engine due to long-term use or insufficient maintenance. Depending on the situation, parts that are malfunctioning, such as pistons and valves, can be replaced with new ones, allowing the engine to be revived with performance comparable to a new engine, enabling it to be used for a long time.
