DELLORTO PHDG. Dell’Orto DNA in Carburettor Form

This morning’s press conference at the DELLORTO stand at EICMA (Pavilion 9, booth I73) served as an occasion to unveil a new product that enriches the range of many innovations crafted by the historic brand from Brianza over its 91-year history. The complete management team of DELLORTO, a fully family-owned company, presented an impactful unveiling of a brand-new carburettor to the press and industry experts, a product that will be available in the coming months.

The carburettor, named PHDG, was conceived, designed, and championed by the engineer Giuseppe Dell’Orto, the company’s current president. Notably, the last two letters of the new carburettor’s name are his initials—a tribute from the entire DELLORTO family to their President. Born in 1940, Giuseppe Dell’Orto holds a degree in mechanical engineering and grew up professionally in foundries and machine shops. He has been the driving force of the company for over 50 years, with a lifelong passion for engines that led him to follow in the footsteps of his father and uncles, the company’s founders. Today, as President, he is still at the forefront, actively supporting the third generation in managing the company and creating new products like the PHDG carburettor.

Giuseppe Dell’Orto, President of Dell’Orto S.p.A.:
“For me, it is indeed a great pleasure to have presented our new PHDG carburettor at EICMA today. This new carburettor, which I see as the natural evolution of a product that symbolizes our brand, is designed for our loyal enthusiasts, who share my passion for engines. It was only fitting to reveal it here, where attendees can admire and learn about it up close. A carburettor, the PHDG, which will then start a range that will be declined in different applications. I am also proud to have introduced it alongside my sons Andrea and Luca and my cousin Davide, who represent the third consecutive generation of the Dell’Orto family in the company. Since 1933, our family business has been designing and developing carburettors, adapting to changes by adding new mechanical, mechatronic, and, more recently, electronic productions. But we have never strayed from the product that truly represents us: the carburettor—a key engine component that stirs emotion. Despite today’s wave of technological innovation, this component continues to evolve, improving over time. The new PHDG was developed with high-performance engines in mind, whether two-stroke or four-stroke, and offers easier access to tuning elements. We aim to reach a wide audience who, like us, are passionate about sportiness and high performance, elements that are at the core of our DELLORTO DNA. These elements also represent me, and beyond the name PHDG—for which I thank the entire DELLORTO team—I believe the carburettor will demonstrate its performance capabilities, expressing exactly what I envisioned since its inception: sportiness, reliability, and innovation rooted in our strong tradition.”

PHDG Specifications
The new PHDG was designed with all the characteristics required for high-performance engines, both two-stroke and four-stroke. The diffuser range goes from Ø18 to Ø24, covering all needs and types of applications. The circular-section diffuser aligns with the intake duct and has an optimized profile for the best flow coefficient and increased air intake, resulting in significant power gains and ease of use. The unique profile of the air intake ensures quick throttle response. The carburettor body, float bowl, and throttle valve are made of aluminum alloy, giving the product lightness and excellent thermal dissipation.

Drawing on racing experience, the main air intake is achieved with a threaded jet, offering ample tuning possibilities. The fuel inlet can be arranged in a diameters from 100 to 225 to meet the demands of high-performance engines. Circuit layouts with or without emulsion holes are available to ensure maximum efficiency and performance across all engine types. The idle mixture screw provides a wide adjustment range with excellent sensitivity for proper idle settings. The throttle valve is in aluminum with a special surface treatment, ensuring high levels of smoothness and wear resistance. The throttle valve cover and float bowl cap are anodized, combining a racing finish with high resistance and lightness. The carburettor body includes a vacuum port and an oil intake fitting with a check valve to prevent accidental filling of oil mixture.
