Hey guys! Let's dive deep into the heart of the 2017 Honda Accord Sport: its engine! If you're curious about what powers this popular sedan, you've come to the right place. We'll explore the engine's specifications, potential problems, and overall performance, giving you a comprehensive understanding of what to expect.

Engine Options and Specifications

The 2017 Honda Accord Sport primarily features a 1.5-liter turbocharged four-cylinder engine. This engine is part of Honda's Earth Dreams technology, designed to offer a balance of performance and fuel efficiency. The turbocharger helps boost power, providing a more responsive driving experience compared to naturally aspirated engines.

1.5-Liter Turbocharged Four-Cylinder

  • Displacement: 1.5 liters
  • Horsepower: Approximately 192 horsepower at 5,500 rpm
  • Torque: Around 192 lb-ft of torque at 1,600-5,000 rpm
  • Fuel System: Direct injection
  • Valvetrain: 16-valve DOHC

This engine is known for its smooth power delivery and decent fuel economy, making it a practical choice for daily driving. The direct injection system ensures fuel is sprayed directly into the combustion chamber, improving efficiency and power output. Additionally, the 16-valve DOHC (Dual Overhead Camshaft) configuration optimizes airflow into and out of the engine, enhancing performance.

Optional 3.5-Liter V6 Engine

While less common in the Sport trim, some 2017 Accord Sports might come with an optional 3.5-liter V6 engine. This engine delivers significantly more power, catering to drivers who prioritize performance.

  • Displacement: 3.5 liters
  • Horsepower: Around 278 horsepower at 6,200 rpm
  • Torque: Approximately 252 lb-ft of torque at 4,900 rpm
  • Fuel System: Multi-point fuel injection
  • Valvetrain: 24-valve SOHC

The V6 engine provides a noticeable increase in acceleration and overall driving pleasure. However, it comes at the cost of reduced fuel economy compared to the 1.5-liter turbo engine. The multi-point fuel injection system and 24-valve SOHC (Single Overhead Camshaft) configuration contribute to the engine's robust performance.

Common Issues and Problems

Like any engine, the 2017 Honda Accord Sport's engine can experience issues. Here are some of the common problems reported by owners:

Oil Dilution

One of the most discussed issues with the 1.5-liter turbocharged engine is oil dilution. This occurs when fuel mixes with the engine oil, reducing its lubricating properties. Oil dilution can lead to premature engine wear and, in severe cases, engine damage.

Symptoms of Oil Dilution:

  • A strong gasoline smell in the engine oil
  • Higher than normal oil level on the dipstick
  • Engine running rough

Causes and Solutions:

Oil dilution is often linked to short trips, where the engine doesn't fully warm up. Incomplete combustion can cause fuel to seep past the piston rings and into the oil pan. Honda has issued software updates to address this issue by optimizing the fuel injection and combustion process. Regular oil changes and ensuring the engine reaches operating temperature can also help mitigate oil dilution.

Turbocharger Issues

Since the 1.5-liter engine is turbocharged, problems related to the turbocharger can arise. These issues can range from boost leaks to complete turbo failure.

Common Turbocharger Problems:

  • Reduced engine power
  • Whining or whistling noises from the engine bay
  • Check engine light illumination

Troubleshooting and Maintenance:

Regularly inspect the turbocharger's hoses and connections for leaks. Ensure the engine oil is clean and at the correct level, as the turbocharger relies on oil for lubrication. If you notice any signs of turbocharger issues, have it inspected by a qualified mechanic as soon as possible.

Direct Injection Carbon Buildup

Direct injection engines are prone to carbon buildup on the intake valves. Unlike port-injected engines, direct injection systems don't spray fuel onto the intake valves, which means there's no cleaning effect. Over time, carbon deposits can accumulate, restricting airflow and reducing engine performance.

Symptoms of Carbon Buildup:

  • Rough idling
  • Reduced fuel economy
  • Hesitation during acceleration

Prevention and Cleaning:

Using high-quality fuel with detergents can help minimize carbon buildup. Periodic intake valve cleaning, either through chemical treatments or manual cleaning, may be necessary to remove accumulated carbon deposits. Professional cleaning services can effectively remove carbon buildup and restore engine performance.

Engine Misfires

Engine misfires can occur due to various reasons, including faulty spark plugs, ignition coils, or fuel injectors. Misfires can cause rough running, reduced power, and potential damage to the catalytic converter.

Common Causes of Misfires:

  • Worn or fouled spark plugs
  • Defective ignition coils
  • Clogged or failing fuel injectors

Diagnosis and Repair:

A diagnostic scan can help identify which cylinder is misfiring. Inspect and replace spark plugs as needed, and test the ignition coils for proper function. Fuel injector cleaning or replacement may also be necessary to resolve misfires. Addressing misfires promptly can prevent further engine damage.

Performance and Driving Experience

The 2017 Honda Accord Sport offers a balanced and enjoyable driving experience. The 1.5-liter turbocharged engine provides adequate power for daily commuting and highway cruising. The Sport trim features a slightly firmer suspension and enhanced styling, contributing to a more engaging driving experience.

Acceleration and Handling

The 1.5-liter engine delivers brisk acceleration, especially in the low to mid-range. The turbocharger provides a noticeable boost, making the car feel responsive. The Accord Sport's handling is competent, with precise steering and minimal body roll. The suspension strikes a good balance between comfort and sportiness, making it suitable for various driving conditions.

Fuel Economy

One of the significant advantages of the 1.5-liter engine is its fuel economy. The Accord Sport achieves respectable mileage, making it an economical choice for daily driving. Expect to get around 30 mpg in combined city and highway driving, depending on your driving habits.

Overall Driving Impression

The 2017 Honda Accord Sport provides a comfortable and refined driving experience. The engine is smooth and responsive, and the car handles well. While the 1.5-liter engine may not offer the raw power of the V6, it provides a good balance of performance and efficiency. The Sport trim's enhancements add a touch of sportiness, making it an enjoyable car to drive.

Maintenance and Care Tips

To keep your 2017 Honda Accord Sport's engine running smoothly, follow these maintenance tips:

  • Regular Oil Changes: Change the engine oil and filter according to Honda's recommended schedule, or more frequently if you experience oil dilution.
  • Air Filter Replacement: Replace the engine air filter regularly to ensure proper airflow into the engine.
  • Spark Plug Maintenance: Inspect and replace spark plugs as needed to maintain optimal ignition performance.
  • Fuel System Cleaning: Use high-quality fuel and consider periodic fuel system cleaning to prevent fuel injector clogs.
  • Coolant Service: Maintain the cooling system by flushing and replacing the coolant at the recommended intervals.
  • Inspect Hoses and Belts: Regularly inspect engine hoses and belts for wear and tear, and replace them as needed.

Conclusion

The 2017 Honda Accord Sport's engine offers a blend of performance and efficiency. While the 1.5-liter turbocharged engine is the most common choice, the optional V6 provides more power for those who desire it. Being aware of potential issues like oil dilution and carbon buildup can help you maintain your engine and keep your Accord running smoothly for years to come. By following regular maintenance and addressing any problems promptly, you can enjoy the reliable and enjoyable driving experience that the 2017 Honda Accord Sport offers. Drive safe, guys!
