Powertrain Control Systems - Integration Solutions Yield Increase in ROI 

Heavy Equipment Factory  

Did you know that Patti Engineering has extensive experience in powertrain controls projects and ongoing support delivery? Not just your standard auto powertrains; Patti Engineering can handle the most complex powertrain controls projects where the manufacturer is building custom engines with thousands of different configurations.


Patti Engineering has longstanding relationships with several of the world's leading manufacturers of medium and heavy-duty diesel engines for the commercial truck and construction equipment markets where we serve as a trusted advisor. We have worked on projects throughout the US as well as in Germany and China. In addition to the manufacturers themselves, we work with the original equipment manufacturers, or OEMs, providing equipment to our client's facilities. In this article we will give you an overview of our extensive experience and capabilities.


MESOur value to our clients is our exceptional ability to take a control system to the next level. Our solutions address the needs of the organization at all levels, from operators, team leaders, supervisors, mid-level managers to executives. From a 'top floor' perspective, what is needed from the plant floor?


With all eyes on the bottom line and ROI, the plant floor needs to operate at peak efficiency with as little down time as possible. Programmable Logic Controllers (PLC's) need to communicate vital build information to the Manufacturing Execution System (MES) which needs to integrate seamlessly with accurate information to enable the Enterprise Resource Planning (ERP) System to facilitate faster and more informed decisions, supporting and streamlining business processes at all levels. Our expertise is bridging the gap between the factory floor and top floor.

Patti Engineering works with OEM's to commission new main assembly lines for various sized medium and heavy duty engines. In this role we serve as the technical advisors to the OEM during commissioning and installation. The vast majority of the equipment at the manufacturers of medium and heavy-duty diesel engines is controlled by Siemens PLC's. Patti Engineering's status as a Siemens Solution Partner ensures the OEM that we can provide valuable Siemens expertise.  


AutomationAlong with supporting lines that we helped install, we have reworked lines that were installed by other OEMs. The reworks were required from our client's point of view because the equipment was hard to support in its current form and did not integrate well with the manufacturing execution system (MES). The OEMs that were responsible for these lines did not have the extensive experience with Siemens that would allow them to deliver the product the plant wanted. Our engineers extensive experience and expertise with all aspects of the Siemens engineering software suite (Ladder, STL, Graph, Safety, etc.) allowed us to develop more robust control systems for the equipment to be more productive, efficient and supportable.


We have served as a trusted resource and partner to several of our powertrain clients on a daily basis for 5 to 7 years. Over this span of time, we have supported as much as 90% of the equipment in the plant. On a daily basis we wear various hats based on needs. We have continued to support various machining and assembly lines, implement new controls to enhance the line and add more features and functionality. Because of our widespread help throughout the plants, we have also spent a lot of time training other engineers, supervisors, team leaders and operators.


MESOur clients look to us to continue our efforts to bridge the gap between the plant floor and top floor. Each assembly line is integrated to the MES. As each part arrives at a new station the PLC performs a transaction with the MES system to receive the build requirements for that particular part. As the work is completed, the PLC reports back to the MES that the work is completed in order to track build history of the engine as well as to keep track of parts used in assembly for inventory tracking. This information is critical for the plant in case the engine has issues in the field.


A Manufacturing Execution System (MES) allows management to keep track of the overall effectiveness of the equipment. We have added tremendous value with the development of MES Systems for our clients. Supervisors responsible for one to multiple lines are able to see how these lines are running, any faults currently active, how much time the fault was active, how long the machine has been running in automatic, etc. With this, detail reports can be generated to get a better sense of bottlenecks, problem areas, or nuisance problems which are occurring thereby highlighting areas that need attention to improve the line. This information is used to look for trouble areas and greatly improves the assembly process.


Heavy Duty EnginePatti Engineering has extensive experience with powertrain controls. Thanks to the intellect, resourcefulness and dedication of our engineers we have been able to support and improve factory level automation, as well as assist our clients in the support and improvement of their MES systems. Call us today to learn how we can assist your company with powertrain controls projects or need for support.

This month our spotlight is on our dedicated and talented engineer, Aju Mathew. Back in the beginning of September, Sam Hoff, president of Patti Engineering received a letter from one of our clients commending Aju Mathew's superior performance on a complicated retool project (click here to see our blog post with the letter). Not only did Aju complete the project successfully, he did it ahead of schedule! "It is not every day that a client will take time to recognize an engineer's performance," said Sam. "Aju is a valuable member of our engineering team; having been with us for over a decade, Aju is one of the reasons Patti Engineering has enjoyed long-term success. Our clients appreciate the commitment, talent and work ethic that engineers like Aju bring to their work."


Aju joined Patti Engineering in 1998 after earning his Bachelor of Science in Electrical Engineering at Wayne State University in Detroit, MI. Recently Patti Engineering gave Aju an opportunity to relocate to Austin, Texas to assist our clients in that market. Aju's technical capabilities and expertise in providing services to a wide variety of industries and clients will no doubt be instrumental in continuing our success in Texas.

"At Patti Engineering we get to do various challenging projects. Being able to be exposed to different projects is one of the reasons to be with the company after all these years. One thing I like about Patti Engineering is the opportunity to work with new technologies, various customers, and equipments all the time. Also, I love being surrounded by a group of talented engineers who are always willing to help if needed. As an engineer at Patti Engineering, I enjoy the constant challenges of moving from projects to projects and the demand of exceeding customer expectations. Although my education has helped me in my career, I believe that my real strength comes from experience. The vast majority of knowledge that I have acquired over the years has been from my various job experiences at Patti Engineering."
