Evo turbo

Types of Evo Turbo

Some common evo turbos include:

• 1. Twin-scroll turbocharger:

  This type of turbo uses two separate scrolls on the turbine and compressor sides. In addition, it captures the pulsations from two adjacent cylinders when they fire. As a result, the twin-scroll turbo increases its efficiency and reduces its turbo lag. This allows the driver to experience a better power delivery.

• 2. Variable geometry turbocharger:

  The variable geometry turbocharger has adjustable blades on the turbine side. Therefore, the angle of these blades can be altered to optimize the airflow through the turbine. This, in turn, improves boost pressure across the engine's entire RPM range. Furthermore, the VGT improves the lag time and increases the fuel efficiency of the engine.

• 3. Electric turbo-compound:

  The ETC utilizes an electric motor to assist the turbine in generating boost. This electric motor can either help spin the turbine or act as a generator to recover exhaust energy. In addition, the ETC improves engine responsiveness while reducing turbo lag. It also increases the overall thermal efficiency of the engine.

• 4. Variable twin-scroll turbocharger:

  The variable twin-scroll turbo combines the benefits of the VTG and the twin-scroll layout. Here, the adjustable blades work together with the twin-scroll design to enhance boost efficiency. The VTS maximizes airflow through the turbine, regardless of the engine's RPM. This results in a broader and more usable power band.

• 5. Dual-scroll turbocharger:

  The dual-scroll turbo has two separate scrolls on both the turbine and compressor sides. This design helps to decrease turbo lag and enhances overall boost efficiency. The dual-scroll layout is mainly applied in high-performance vehicles, as it provides a quick and linear power delivery.

Specification and maintenance of evo turbo

Specification of evo turbos can help businesses and end-users understand the product better. So, let's check the specification of the turbocharger:

• 1. Turbo Type

  Single-turbo: The most common type of turbocharger used in vehicles. It is powered by a single turbine and compressor.

  Variable Geometry Turbocharger (VGT): This kind of turbocharger varies the size of its vanes (blades) in real time to tailor the amount of boost needed depending on engine load, improving efficiency and performance.

  Dual-scroll Turbocharger: It divides the exhaust gasses into two channels corresponding to its two turbine and compressor sets, improving efficiency and reducing lag.

• 2. Turbo Material

  Turbine and compressor wheels are often crafted from inconel (a nickel-chromium alloy) or titanium alloys for superior strength and heat resistance.

  The turbine housing, compressor housing, and wastegate actuator are generally constructed from cast iron or aluminum for their durability and heat resistance.

• 3. EVO Turbo Size

  Small turbochargers (less than 1.5L): suitable for small engines; they help improve fuel efficiency and increase power output without needing larger engines.

  Medium turbochargers (1.5L to 3L): these are the most common types of turbochargers found in vehicles today. They balance performance and fuel efficiency. Drivers can experience a boost in power without compromising fuel economy.

  Large turbochargers (more than 3L): suitable for high-performance vehicles. They produce more power but can lead to reduced fuel efficiency. As a result, drivers need to refuel more often.

• 4. Compressor Trim

  Compressor wheel diameter: 50mm to 75mm. This determines how much air the compressor can move, affecting boost levels and engine performance.

  Compressor wheel material: Billet or cast aluminum. Billet is more durable, while cast aluminum is lighter and less expensive.

  Compressor trim size: A/R ratios range from 0.5 to 1.5, affecting how efficiently the compressor moves air through the engine.

• 5. Turbine trim

  Turbine wheel diameter: 50mm to 80mm. This size impacts how much power the turbine can extract from the exhaust gases, influencing boost levels.

  Turbine wheel material: inconel or titanium alloy. Inconel is extremely heat-resistant, while titanium alloy is lighter and better for high speeds.

  Trim size: A/R ratios varying from 0.6 to 1.2. This affects the turbine's efficiency and how well it converts exhaust energy into boost.

• 6. Bearing system

  Ball bearings: These provide a smooth and stable spinning experience, reducing friction and increasing boost response time.

  Piston bearings: These are more common in budget-friendly turbochargers. They are less expensive to make but require more maintenance than ball bearings.

  Bearing material: brass or bronze for durability and heat resistance.

• 7. Wastegate type

  Internal wastegate: It is located inside the turbocharger housing and is more compact.

  External wastegate: This is placed outside of the turbocharger, allowing for better boost control but requiring more installation space.

Here are some general guidelines for maintaining the evo turbo:

• 1. Keep the oil clean and full. Oil helps the turbo spin smoothly. Dirty or low oil can cause damage. Change the oil every 5,000 miles or as suggested. Use oil filters to trap debris.
• 2. Allow time to cool down. After driving hard, let the car idle for 1-2 minutes. This cools the turbo before shutting off.
• 3. Clean the air filter regularly. A clean filter allows good airflow to the turbo. Wash it every 10,000 miles or sooner in dusty areas.
• 4. Check hoses and connections for leaks or cracks. Replace worn parts to keep boost levels normal.
• 5. Monitor boost pressure with a gauge. Low pressure may indicate turbo issues that need fixing.
• 6. Do not exceed the manufacturer's recommended rev limits. High RPMs for too long can stress the turbo.
• 7. Follow the service schedule in the owner's manual. Timely maintenance prevents turbo problems.
• 8. Avoid excessive idling. Prolonged idling can overheat the turbo.
• 9. Don't overload the vehicle. Too much weight strains the turbo.
• 10. Drive smoothly. Hard acceleration puts extra stress on the turbo components.
