Variable Timing Valve Train (VTVT) is a system which has the ability to have independent control of the intake and exhaust valves in an internal combustion engine. In VTVT engine technology the timing of intake and exhaust will be independently programmed in different engine load criteria..
Then, which engine is better VTVT vs VVT?
VVT name is used by Maruti Suzuki whereas VTVT is patented on Hyundai's name. Both the technologies work to improve fuel efficency and volumetric efficiency by changing the inlet and exhaust valve timings depending on the speed and load conditions. NOTE- Honda's i-vtec tech is also same as VVT and VTVT .
Secondly, what is VTVT and CRDi? These are the abbreviations used to denote the fuel type of engine in Hyundai. Here, VTVT(Variable Timing Valve Train) used to represent petrol engine while CRDi ( Common Rail Direct Injection ) used to denote diesel engine.
Just so, what does VTVT stand for?
Variable Timing Valve Train
What is a dual VVT engine?
Dual VVTi stands for Dual Variable Valve Timing Intelligence. Where in addition to intake valves, exhaust valves also controlled electronically. In both cases intake or exhaust camshaft Timing sprocket can independently rotate within camshaft.

What is the advantage of VVT engine?
Benefits of VVT One benefit is an increase in maximum engine speed (and therefore more peak power) – as much as a 25% increase. Low speed torque is also increased, providing better handling and drivability.What is the meaning of I DTEC engine?
I-DTEC stands for Intelligent Diesel Technology Electronic Control. Yes it's turbocharged. It's a lightweight aluminium engine which is differ from I-VTEC. New generation Earth Dreams series engines are very fined and high end technology aims reducing the carbon footprints. Good fuel economy.What is Ddis?
DDIS (Diesel direct injection system) refers to the type of diesel engines for cars . They are equipped with turbochargers, which increase availability of oxygen, resulting in better combustion thus increasing the engine performance.What is mean by VVT?
In internal combustion engines, variable valve timing (VVT) is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems.Is VVT the same as VTEC?
In an automobile engine the intake and exhaust valves move on a camshaft. i-VTEC uses not only timing but also the lift aspect of the valves, while VVTi uses only the timing aspect. The technology that uses timing and lift aspect developed by Toyota is called VVTL-i and can be equated with that of i-VTEC of Honda.Is VVT engine good?
The increase of power in the upper parts of the rev range is great, but the low-down torque is what makes VVT so usable. Thanks to more precise handling of engine valves, VVT makes engines significantly more fuel economical than their non-VVT counterparts.What does i VTEC stand for?
Acronym. Definition. I-VTEC. Intelligent Variable Valve Timing and Electronic Lift Control (Honda)What is CVT and VVT?
CVT is a transmission. Continuously variable transmission - Wikipedia. VVT is variable valve timing. Variable valve timing - Wikipedia. VTEC is Honda's trademarked name for VVT.What is the difference between i VTEC and VTEC?
i-VTEC - intelligent Variable valve Timing and lift Electronic Control. The only difference between this i-VTEC engine and the older VTEC engines is the addition of the VTC system. The intake camshaft has the automatic self-adjusting cam gear which continuously optimizes valve overlap for all RPM ranges.What is VTEC kick in?
VTEC = Variable Valve Timing and Electronic lift Control. And there is a kick in. The system works on demand. The system is activated when you reach a certain RPM( I have an accord they differ with the motor), oil pressure and speed. The system works off oil pressure and is engaged by a VTEC solenoid.Are VVT and CVT the same?
Yes, one is transmission technology(CVT) and other being Engine Valve(VVT) technology.What is VVT direct injection?
“The VVT (variable valve timing) system is tuned to work in tandem with direct injection to achieve optimum fuel economy and lower emissions. With direct injection, fuel is sprayed directly into the engine cylinder, where it is mixed with air. As the fuel vaporizes in the cylinder, the air and fuel mixture is cooled.What is VTEC engine technology?
I-VTEC stands for Intelligent Variable Valve Timing and Lift Electronic Control. It's developed by Honda to improve the fuel economy of the engine. It's Spark ignition(Gasoline) engine to develop the volumetric efficiency of the four stroke IC engine. It's not a Compression ignition(Diesel) engine.Which is better TDI or Crdi?
“CRDI” is for “Common Rail Direct Injection” while TDI is for “Turbocharged Direct Injection.” Common rail direct injection or CRDI is now a widely accepted design for diesel engines. Like any other diesel technologies, CRDI has proven to be fuel efficient and boosts the engine's performance.What is CRDI 16v?
CRDi stands for Common rail direct injection which means direct injection of fuel into the cylinder of a diesel engine through a single common line called common rail which is connected to fuel injectors. In conventional diesel engines, there will be as many pumps and fuel rails as there are cylinders.Is Crdi a turbo?
CRDI engines are turbocharged power units installed on Hyundai and Kia vehicles. The advantage of CRDI engines is their efficiency, and reduced content of harmful substances in the exhaust.What is the meaning of Kappa engine?
Kappa engine is fuel saving power unit that was developed by Hyundai. Hyundai uses new technology to develop Kappa engine that cut weight and friction to boost fuel economy.What is CRDi system?
Common-rail direct fuel injection is a direct fuel injection system for diesel engines. On diesel engines, it features a high-pressure (over 100 bar or 10 MPa or 1,500 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles).What is Crdi in Hyundai?
CRDI stands for Common Rail Direct Injection meaning, direct injection of the fuel into the cylinders of a diesel engine via a single, common line, called the common rail which is connected to all the fuel injectors.
